Kitty thanks for writing your heart-felt instinct, bang on the nail, as always.

I think it does scale, infinitely, like solar power, once we put our best minds to it, and the elimination of the problematic profit-driven economy.

It will happen automatically when that source is introduced to our economy very soon, when it is realised that is the real reason free money works, we can assign all human debt to be paid back down by appropriate installation of industrial scale solar power, then amazing things will start to happen again, like we saw when massive stimulus was issued previously by the orange renegade.

By that means, scarcity, the main vital component of profit is removed, forever.
