"I interpret you as hoping for redemption."

I don't understand redemption in this context, unless you mean salvation, in the Christian sense of being redeemed by a saviour that has paid some magical cost of sin. If that is what you mean, I absolutely do not mean that. I rather note that since owning means of production of food, money, communications, electricity, and etc., are more profitable to the consumer than buying those products and services, then consumers will acquire and produce with those means as soon as they can, and it is the knowledge of how to use them that is the highest hurdle we face.

This doesn't require a saviour other than the sinner themselves fixing their problem, in this case of dependence on overlords for their necessary and desirable goods and services.

"The 3D printers need to be filled with something, where does the filler come from if you can't make it yourself and where does the 3D printer come from if you can't build it yourself?"

3D printers can use every material humanity has ever used to make things with. From chocolate frosting to individual atoms, from mud and sticks to plastic and steel, additive manufacturing has been prototyped with such materials successfully. The core technology is the movement of a printhead by cartesian coordinates, and variable printheads and materials with appropriate metrics for automation. The rep rap movement early on designed to make 3D printers follow an exponential growth and dispersion throughout the population, while using the most crude and early prototypes of the technology. As the technology continues to develop and become ever easier to use, it will more broadly disperse and continue to add new kinds of products and materials, from moon dust to liquid water from vapor in desert air.

It's difficult to grasp how profoundly additive manufacturing technology will affect society. Assembling molecules from atoms enables an incredible array of nanotechnology, as well as making pharmaceutical corporations completely unnecessary, and tyrannical efforts to control what people put into their bodies irrelevant, because such tech can print morphine or graphene, nanobots or water, vaccines or bullets. It's not just elimination of parasitic losses, it's expansion of human freedom beyond our ability to even imagine.

Every new technology builds on prior development, and every decentralized means of production also does. However, it is not possible to prevent using the very common parts and supplies necessary to make the many decentralized means of production from what is available inexpensively. Aquarium bubblers, gutters, buckets, and LED lights, deployed in a particular way, are able to create aquaponics setups that can provide all the food necessary for the user. The invention is not the bucket or lights. It's how to use them to produce fish and plants for food. Ordinary inkjet printers can print solar panels using commonly available inks and plastic sheeting. Code and internet access is all that is necessary for cryptocurrency. What makes these things able to produce goods and services is how they are used, and these commonly available resources can't be controlled to prevent their use for that purpose without extreme disruption.

It's just using what we already have better. If extruded aluminum bars (used for the three axes support structure of 3D printers) aren't available, plastic, steel, wood, or even ceramics can serve. Small electric motors are practically ubiquitous and won't be unavailable to 3D printer makers without crashing civilization practically back to the Stone Age. You really can't print one today, but you really don't need to. They can be made by hand, and the ores can be literally dug out of dirt and smelted and refined by hand if necessary. Decentralization is simply how technological advance can improve productivity from where it is today.

Technology evolves according to the laws of physics, and each milestone is the map to the next. We cannot change the laws of physics, and all that can prevent the natural progression of technological advance is to end technological advance. What seems to be happening is that overlords seek to genocide plebs and enslave the GMO survivors, so only they enjoy technological advance. I don't think they can, and only their psychopathy and narcissism causes them to even try.

"...you have to go from being just a user to being an understander."

This is the nature of technological advance. However, automation changes everything. I am willing to bet you do not understand how your cell phone's parts all work, and the same is true of your car, and the fasteners in the walls of your home. We don't need to understand the inner workings of these mechanisms. We only need to understand how to use them. 3D printers, aquaponics, mesh networks and etc., are all still in the enthusiast stage of development, and individuals tinkering with them do so mostly because they are hobbyists. It's facile to see how that will change, and is changing, so all we have to do is just use them as they are designed and don't have to understand infernal combustion and crankshafts to drive across town, or print a sheet of graphene.

"An autonomous household can neither produce petrol nor generate electricity without again relying on central resources and technologies."

This is not true. During WWII Europe suffered extreme lack of petroleum available to civilians. People fueled their cars with wood, which is pretty easy to do.

"The first case of printed electronics was seen in 1903 when Albert Hanson filed a patent for "printed" wire. After that the radio drove the industry of printed electronics forward. Until recently inkjet printers have not been used in the printed electronics industry. Industry has decided to move towards inkjet printing because of its low cost and flexibility of use.[8] One of these used is the inkjet solar cell. The first instance of constructing a solar cell with an inkjet printer was by Konarka in 2008.[9] In 2011 Oregon State University was able to discover a way to create CIGS solar cells using an inkjet printer. In the same year MIT was able to create a solar cell using an inkjet printer on paper. The use of an inkjet printer to make solar cells is very new and is still being researched"

The evolution is underway, but solar panels can be printed right now.

"you are perpetrating a fallacy...by setting up saviour scenarios."

I don't really understand this. I'm just taking advantage of the technology available and looking forward to how technology will evolve. No saviour required. I am the only saviour I need, and what I intend to be the take away from my post is that you are the only saviour you need. We are the creators of the world we live in, when we make it.

Make it.
