all of these will be "old concepts" that don't mean much anymore.

Instead of a fixed, ball earth, with moving plates, another idea that works is the expanding earth. The continents moved apart as the Earth expanded. Making lots more material to provide for more material needs.

The Earth grows enough food for everyone, it is just that it is blocked from getting where it needs to go.

And, without consumerism and advertisement, people usually get sated in the amount of things they have.

"Money" will go away when we no longer need it. Which has a lot more to do with each of us learning our capacity to give, and not exceeding it.
