Earlier quoted context omitted.
Did you even get my point that communism is different from socialism? I very much stated exactly that communism (in my opinion can’t work either). But socialism as a spectrum of ideas has plenty of working aspects included in basically every Western democracy.
Socialism produces mediocre works, and can't compete with free market operations. This is why socialist operations tend to be heavily subsidized or they simply make free market competitors illegal. 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.
