Pretty much this, unless of course we're talking about some distant society where new technologies and new forms of rationalization of the economy have made stuff like that have made trade and exchange as we know outdated.
I'm also kind of skeptical of how much people who are for a moneyless society (with present technology/information) have thought their ideal society through.
Yeah there wouldn't be a new medium of exchange based on a widely accepted commodity or anything (like cigars used to be in prison)
Those who say "no" are being subconsciously misleading.
The proper answer is "I don't know; I couldn't conceive of such a system myself with my current knowledge or lack thereof."
Communism.
Although, it's about creating such tech, I tend to believe we already have/could have in short time, the tech to go fullcommunism.
Cigars in prison! That's another good example. I forgot about that.
Capitalism can go fuck itself but a money of some kind will always exist and trying to ban people from using a money would work about as well as trying to ban them from giving each other gifts and presents.
Bitcoin. But it can only happen in a educated society (automatically white).
Prehistoric men, antique slaves, Middle-Age peasants, all of them lived without money.
Commodities in general were an exception, and the fact that this exception became a rule is precisely what defines capitalism. There will be no more money, no more commodities in communism.
Simple: picture yourself living the exact same day as usual, only without anybody asking you, or giving you money.
Go listen to some David Graeber. Moneyless economic interaction between people, based on credit, usufruct or gifts, have been the norm for much of rural/village society. Money as a medium of exchange is only necessary in larger, complex societies where you're interacting with strangers and across long distances.
I agree that current states couldn't survive without money; we'd need some kind of transitional system of credit or barter, or a lot of computerized central planning. But at the truly local level, moneyless interaction can easily be returned to.
