Let's rephrase it without the cappie propaganda. If you're trying to donate your artwork to the king for peerage with the lesser nobles, and THERE'S NO KING OR NOBILITY, how's that gonna work?''
Now, if someone kidnaps you and drops you in a remote wilderness location, which of these trees, bears, etc are you going to try to exchange the little slips of paper for goods and services with, and how's that going to go?
If you wake up tomorrow, and the entire human population has vanished, but all the material crap is around and all the doors are unlocked, what are the nonmaterial social conventions going to do, exactly? Money, law, etc - where'd it all go?
You can't trade artwork to the king for gain in a nonmonarchy because it's a nonmonarchy. You can't trade money to squirrels in the wilderness because it's a nonmonetary environment. There won't be a whole lot of profit in a postcommunist society because it's scenario #2, the postapocalyptic world where there is no one to honor your spooks, but with other people.
I mean, don't get me wrong; you could whip out a computer printer right now and print yourself a bunch of paper slips with pictures and numbers on them. Most people skip it because there's no point, though. And the "special" paper slips work about the same in squirrelland, postapocalypta, and communism (or postcommunism).
Getting there yet? Because, yeah, there's technically a brief risk of communist-agorist living in the ten minutes or so before someone says "fuck it, I'll just whip out a gift economy with these unowned, open-access MoP," but it's expected to delve into postcommunist society pretty damn swiftly. That's the postapocalyptic world, but with others playing in the now-unowned shell of the old, too.
