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.

There are plenty of examples of open sharing systems that are functional.

Science, for example. Nobody ‘owns’ the formulas that calculate orbits or the underlying mathematics that AI models are built on like Transformer networks or convolutional networks. The information is openly shared and given away to everyone that wants it and it is so powerful it has completely reshaped society everywhere on the Earth (except the Sentinel Islands).

Open Source projects, like Linux, are the foundation of the modern tech world. The ‘IP’ is freely available and you can copy or modify it as much as you’d like. Linus ‘owns’ the Linux project but anyone is free to take a copy of the Linux source code and modify it to whatever extent that they would like and form their own project.

Much of the software and services that people use are built on top of open source tools made by volunteers, for free; and most of the useful knowledge and progress for human society results from breakthroughs made in the sciences, who’s discoveries are also free and openly shared.
