I'm not seeing the connection here. By the same logic, nobody needs software, it's ok if you can't use software, thus proprietary software is not unethical?

By that logic nobody needs game developers and it's OK if we remove any laws (e.g. copyright) that protect them.

I don’t see how you arrived at that conclusion. People pirate games as if they’re entitled to play them without paying. If someone can’t afford the game they want, too bad. There were plenty of games I could not afford as a kid, so I did other things.
