This is why concepts like UBI would be so transformative to society.

Imagine a world where no one had to choose between creating and surviving. Where writers and artists and coders and musicians could just make beautiful things and give them to the world for nothing.

Coding isn't always compensated. Open source projects thrive because of the work of developers that don't get paid in most cases. That doesn't stop them (although it's probably because they do other work and can spare time and money).

My point is that both, art and coding, don't require compensation. Many people do both for the sake of it.

That doesn't mean they don't deserve compensation (in the form of donations). They do, most than any other.

I'm fine with compensation, I'm not fine with the whole work once and siphon off the labor of others into eternity.

People who can't pay experiencing their creative work doesn't take anything away from them. Complain about the lack of funding for art instead

What if code should also be shared freely?

It is a statistical fact that people who pirate things tend to buy more things than people who never pirate anything. Furthermore, people who exclusively pirate are a minority. It is also a fact that the majority of pirates would rather pay for things if the service provided is a superior experience to that of piracy.

Gabe Newell said "Piracy is almost always a service problem and not a pricing problem."

Don't do work that requires uploading your work to the internet before being paid if you're not okay with some people experiencing it for free.
