Well, the first step will be small communities with their own, non-polluting, continuous energy systems.

on the money thing, we will shift to crypto (so no more money printing) and then we will shift to a person backed money, where people have worth, the currency is measure in.

then it is… something to do with inter-small-community settlement layer thingy.

And after a bit more, people will feel they really do not need the money (after everyone learns to give and get)
