We tried the "trade your skills for something you need". In every surviving society it eventually lead to the development of a currency (not hard to see why), which requires/leads to regulation, which requires enforcement, aaaand you're back at a modern society. I'm all for more regulation to reduce economic and social differences in society, but the people that are talking about abolishing governments and currencies need to pick up a history book and follow their ideas to their natural conclusion.
"Controlling speech" is a hallmark of authoritarian governments, be they far-left or far-right, there are plenty of historical examples of both.
