Sure, people won't work at Amazon, or plow the fields. You could say this is a problem. What I see is a bigger problem: 'cementing' the absolute authority of The State, turning The State into a 'cradle-to-grave' definition of a replacement of society as such. UBI would legitimize this complete overtaking of society, which is always the agenda of humans such as those who created, own and control The State.

Production is a purely practical concern. The problem, so to say, in Brave New World was not a lack of physical resources. Once they've cut the population down to these 500 million, all kinds of automation and robots will probably be more than able to provide food, clothes, technology and drugs to cover all needs, but humanity will then be barn animals or pets...

Communism is the anti-reality agenda of making up a society on paper, literally on paper, that conforms to 1) some ideological notion of how the world ‘should’ be, and 2) is created, owned and controlled by the Communists. The prominent part of Communism is that it’s anti-reality. Its failure to make a functioning society, is simply a consequence of that, and not any ‘defining trait’ of Communism. Give these people enough time, and they’ll diligently find ways to solve the problems they come across. You can look at how they rigged the U.S. Election, how they own academia, media, that is both news and entertainment, Internet, religion, and so on…

Failure is not a necessary part of anti-realityism, and in the long run, people can figure out a lot of things. Being a Communist is about a particular social attitude, not about being an otherwise normal human but just low in IQ. When I say ‘purely practical concerns’ I don’t mean practical concerns as such but concerns that are nothing but practical. That would mean for example that on a purely practical level, cannibalism is ‘expedient’, and so is killing one’s own offspring. Purely practical concerns is amoral utilitarianism. Again, the book Brave New World is about this one, single topic.
