The IP of how to do things (patents) is made up and detrimental to society. Other IP such as brand names is reasonable, we don't want people saying they're selling us Coca-Cola if it isn't from that particular manufacturer. If there are ways to make stuff, everyone should be allowed to try, because it's in setting up the complex web of inputs and bringing the product to market that people benefit. The advantage of free markets isn't that it allows the US to make IP, it's that it lets various people have a go at supplying something that people want.
