you actually have to "go outside" and "build some communism" to learn how to be a communist. not all knowledge comes from books and articles, and you can learn a lot from IRL organising
seriously. it's not that big a deal. if people in gaza are still standing up to their oppressors every day then you likely have zero excuse for not doing more IRL shit (political reading and writing at home are good, but don't mean anything if you're not applying that theory as practice and then assessing the results and adjusting your practice accordingly).
Like the Chad/Chaz zones in 2020? They tried already. Would have been cool to see that stay real just to see what would happen... But it got slaughtered by fear of differences. And I'm not saying this as a "communist". Fear, difference and lack of faith is murder of real freedom. And that's something we're all reminded of daily regardless of sides.
Chaz failed because it was a spontaneous uprising that devolved into a disorganised mess due to ideological incoherence which led to it having no proper resident organisational structure and thus no authority to administer or govern the pop up municipality without being capable of demonstrating a popular mandate of the residents. Not because autonomous zones are a bad idea.
If the ideological contradictions had been resolved then proper organisation could have occurred, a council could have been formed of the residents, and a real structure of authority built. This would have solved the vast number of problems that occurred as a result of the authority power-vacuum that formed.
