Avoiding tax loopholes and fair taxation for billionnaires could also be considered. Just saying. Otherwise I think that the idea of deleting all IP laws is just wishful (and naive) thinking, assuming people would cooperate and build on each other’s inventions/creations.
Given the state the world is currently in, I don’t see that happening soon.
I agree with most of what you say, nevertheless I’d like to underline that my context was broader and not limited to Linux and open source, but to a greater extend to topics like inequality, world hunger, wars, access to infrastructure, education and healthcare for example.
