The US ones did not fail because some more aggressive group overtook them. They failed because they did not work and eventually the members tired of it and left.
The state-sponsored kibbutzen in Israel also fail, because they can't exist without massive government subsidy.
Communism has been tried many times on a nation scale. 100% failure.
Your ideas are not new and they have been tried, again and again. They just don't work. They don't work on a small scale, they don't work on a large scale. They don't work when voluntary, they don't work by force.
There is just something about communism that is fundamentally anti-ethical to human nature.
It's most obvious when agriculture is socialized, because it's impossible for people to believe the lie that they aren't starving.
Yes, I know that communism is supposed to be without a government.
The only entity capable of creating such a market is the government itself. Also, don’t forget that plenty of areas simply don’t operate on a supply-demand basis — e.g. healthcare.

Supply-demand is in play even under socialism.
But here's a simple example. Take your corner drugstore. It has a couple aisles of all sorts of healthcare products, from aspirin to toothbrushes to athlete's foot cream to cold remedies. There are multiple brands with multiple formulations at various price points. How does supply & demand not apply there?
More generally, pick any health care issue. For each, there are a multiple of options available, with varying costs, efficacies, risks, and pain. Including doing nothing (by far most diseases disappear on their own). How is that not supply & demand?
But even in today's capitalist system UBI could be implemented relatively easily paid for by tax money.
