Funny enough I was writing about precisely the same complex equilibrium with "greed only" at one end of the balance and "complete communism" at the other in a comment on a @jamesbrown musing over why there's no fusion reactor yet, despite the fact that it has been predicted for almost 50 years now.

The overall consensus is that the oil and gas lobby has no interest in a fusion reactor becoming a reality. That is a matter of course but the horse industry had a strong interest in the young automobile failing at the end of the XIXth century and that didn't prevent the car taking over the world.

It's clear that the greed of the oil and gas industry will fuel a fight against the successful development of a fusion reactor. So pure greed is not good.

But the key is to understand that if pure "A" (say greed) is BAD, it doesn't necessarily imply that "Not A" (say communism) is GOOD.

And I was giving the example of Europe which took the radically opposite approach of eliminating all source of greed and putting the task in the hands of civil servants. No greed whatsoever because no financial or monetary incentives involved.

Whether that is the right approach it's pretty easy to see: where's Europe's fusion reactor ?

My point here is that the order is important: we will not "think of crypto as tokens more than currency" first and then "the mind set will change". Rather, thanks to technological progress, we will avail ourselves of everything to our heart's content. We are heading toward a world of abundance. That won't abolish greed, which is, to various degrees, part of our genes. But the greed level will decrease.

And then, thanks to greed decreasing (but never going to zero), we will both change our mind set AND start looking at crypto as tokens. The "currency" will be less and less needed because there will be less need for exchanging stuff - more and more stuff will be available to everyone
