I disagree with every one of your points.
The only place that UBI has worked has been straight charity. Where you have people looking in on how the recipient is doing. And that makes all the difference. The difference between that and welfare.
Welfare creates ghettos. I have never seen it create anything else.
And yes, i shouldn't have used the word communism, i should have used the word extreme socialism. And i probably shouldn't have used the word capitalism.
Because, neither capitalism nor communism is a thing that can be run by the state. They exist in the people. And both have only a handful of actual examples of them working.
And you really need to learn about the costs of manufacturing. You believe in the Marx definition of the proletariat. Well, it doesn't work that way. In the future you are wishing for, there are no factories. Just like the USSR was becoming.
