If you don't respect the copyright the government will use force to confiscate your money. If you can't refuse it, they will escalate their demands up to a violence. Government has a monopoly on violence which it controls and delegates.

It's a monopolistic practice because it essentially enforces that only a certain party might use intellectual property, even though you can't own a thought.

The only flaky part of the argument is that it is abused by wealthy, but when you look at the rate of patents corporations put out every day, the disproportionate copyright enforcements and the fact that these corporation lobby and historically have lobbied for stronger IP protection laws, you would agree.
