Did you know 3D printers can print water out of thin air?
Nope, I didn't know that.
And yes, I find everything else you've said in your comment potentially feasible. But as I also hinted in my previous comment, we have to be aware that they will not make things easy for us to take a step forward and get things done without them trying first to avoid its feasibility by going openly into authoritarian and tyrannical fashion just to prevent us from breaking free from their current control, power and influence.
It's difficult to believe that the ability to bring these potentials to fruition isn't going to become existentially necessary to survival, because a global collapse of the economic system is being engineered, national polities across the world have been infiltrated by WEF trained traitors, and WWIII is breaking out from N. Africa to the Ukraine.
Folks that want to prosper should be adopting the means of production suitable to their personal circumstances, but pretty soon anyone that wants to survive at all may have to.
