As for this "give and give and give..." Did You miss the taking of what You need or want? You cling to the idea that We must get something in return for doing something We love to do.

i did not miss it.

You NEVER take.

Sure, you are probably imagining commodity goods that are all identical, but in the future, those will be fairly rare.

One off pieces of art will be the norm for pretty much everything.

i am sure that you imagine a huge pile of toilet paper and everyone just taking what they need. But even if its a commodity as ubiquitous as toilet paper, there was still time and energy that went into its creation (besides electricity).

And the energy exchanges need to be well balanced.
It is far more important that you are currently thinking.
Like avoiding WWIII level of importance. (and i am not speaking figuratively)
