Like, people should be allowed to remove stuff from the Internet that they’ve created if they want,
No, no they shouldn’t. This is antithetical to the generally good intention behind copyright.
The point was not to allow people to take away things they have created, but to permit them to profit in order that they might choose to make more, and be able to support their life in a capitalist system. These intentions are largely good.
Allowing people to take away what they have created is the opposite of this intent, and harmful to the public good, which benefits from as many works as possible being accessible to the public.
