People are most comfortable with what they are familiar with. People are very familiar with the idea that "somebody is in charge." The issue, is that when you put somebody in charge, they become disconnected from the rest of the society, and this leads to all manner of problems, such as corruption, and elitist politics that treat ordinary people as inferiors to be exploited.
One could argue that without "Somebody in charge", there is no central power structure around which to enforce the protection of the commons, and this leads to a runaway degeneration and destruction of the actual communal wealth of a society through lack of planning, general wasteful mismanagement for the sake of convenience, and a number of other maladies.
I am just waiting for non-human artificial general intelligence to actually become a thing. Theoretically, such an intelligence can be designed to never become corrupt, would have the necessary mental capacity to directly interact with all citizens of every level of society at all hours of the day, every day, for eternity-- and thus would not suffer from the ideological disconnection that causes the slide toward elitism-- and further, could be designed to see to all human needs properly. It would make the ideal government possible.
People I mention this idea to act like I have suggested worshiping satan though-- the idea is so unfamiliar and so alien to them, that they instinctively fear: What if the machine hates us, or decided that we are not necessary? For them, I point out what AI actually is, and how it actually works-- such outcomes would be antithetical to its core programming, and make about as much sense as wondering if a calculator could find that 2+2=5. The real threat would be humans, who having been kicked off the gravy train, seek to reprogram or replace the AI to better suit their wishes, and to re-create elitist classes of privilege within society so that they can feel important without actually contributing to anything other than suffering.
I really feel that if something like communism were to succeed, it would require such a non-human intelligence to be its arbiter.
