If we were a space-faring people with automated robots doing space mining, collecting and processing materials, if there was no shortage of resources and nearly everything was automated - then sure, fine, people can have their utopian space-communism, culture-series, setup where everyone gets free money and can have whatever they want, and do whatever we want.

But we're so many lightyears away from that situation. Our resources are very much limited. If people don't keep producing, we just stagnate and decay. We're nowhere near the point we need to be.
