That’s making his thought into something it definitely is not. It’s not a system. The idea of the union of egoists is that it is the only possible truly free association between people. Under communism, all associations would be union of egoists, and no one would ever think about them or even have that name for them. They would just exist, and do things with other people for different purposes at different times, always only when it’s beneficial to all involved, and stopping when it stops being beneficial for any party.

Or isn’t communism the total liberation of the individual? (among other things ofc, but to me it was always the main one tbh, in how I understand things - not a libertarian or anything)
