Companies such as Disney have armies of lawyers to enforce their monopolies. Copyright and patent laws are designed exclusively for the rich.

Disney can very well “steal” other people’s work and get away with it under this system. Without such laws, everyone else would be able to “steal” from Disney as well, which would level the playing field.

Copyrights and patents are literally government enforced monopolies for huge companies. Without them, there would be a lot more competition.

You are correct. There would be no copyrights or patents in a free market.
