A world with “no money” need not be a dystopia. After all, money and prices are simply the most efficient method we’ve found for distributing scarce resources.
Scarcity is and of itself not a good thing, but a bad thing. The problem is that humanity has of necessity been organized since it began to develop organization essentially to divide up scarce resources.
When scarcity disappears, at least for many things, then how do we organize ourselves?
As the most obvious example, gaining access to the world’s knowledge used to be very difficult and expensive. Today it is utterly free. Doesn’t mean we use it any more wisely.
Money is just a medium of exchange and there will always some kind of medium of exchange for goods and services and other assets.
I don't mean to pick on you, but you have made the most interest points here.;-)
Scarcity can be a good thing in that it can build character.
Like many of us, I had parents who were children of the depression. Their appreciation of the value of little things (like a hot cup of coffee and a good meal) were the products of scarcity...and were wonderful things to behold.
It's clear that nobody is really preparing for this transition, which is why it's bound to be rough.
