I'd take things a bit further than just communism. I'd imagine a world where farm and factory are all largely automated and publicly owned.
Anyone who wants a role has one, but no one is punished for not. Housing and food are guaranteed to all, as are most small luxuries.
Want to make the world a better place? Do it. Science and Tech would be fully funded. Want to sit around and just sort of live? Sure, you get UBI.
The only work places not owned by the workers would be the ones owned by government. If it's an essential service, it's government owned and government operated. If it's for fun, then sure, let some people get together and work toward making something fun.
Another change; copyright and patent law would be maxed at 14 years. That number has actually been shown to be when 97% of the profit is made on most copyrighted work. This one change would open up so much potential for public domain creativity.
I'd allow for continuing trademark of character, if they were in continuing use. i.e. a sort of serialization exemption to the copyright limits. If the author keeps putting out new material, they get to keep a form of control over their works, but if they stop, then it's all public domain.
I may have put a lot of thought into this over the years, and parts would still likely need to be adjusted during implementation.
