Hello! So many questions...

Printing drones for what purpose? Who will identify the target?

Do you use alternative energy sources? Why are they 5-7 times more expensive than grid power?

Have you dug your own well to irrigate your hydroponics? Why do organic farm fruits cost many times more than chemically produced mass-produced fruits?

Where do you get your seeds? How do you know those seeds are not gmo, is someone responsible to you for that?

Do you know that plants do not feed on water alone and it is unlikely that you can produce all the necessary micronutrients for a nutrient solution at home? Do you have experience?

About 3D printers!
Only the hull of the spaceship was printed on a printer, and that's not even half of it.
When you buy a printer, you become dependent on the manufacturers of the materials for it. Correct me if I'm wrong there is no printer printing from recycled materials.

It's a vicious circle. To buy a house with land - you need money, to buy a printer, a generator, aquaponics with fertilisers, seeds, you have to go to work as a slave! And slaves are not paid enough to achieve independence!

I agree that it is worth striving for, like any good utopia. It will cease to be a utopia when there is a legal way to earn money for everything you need in a legal way

Who can afford it?
