Another part is trademark law. It should not be possible for e.g. coca cola to make Pepsi cans with horrible tasting drinks inside.
However, most of Patent law, and a lot of Copyright law should be scrapped.
The social norm against plagiarism is plenty strong.
It's so strong, in fact, plenty of people think copyright law prohibits it.

And this is why trademark law shouldn't have been swept up under the illusory banner of "Intellectual Property" to begin with: Rightfully considered, it's a consumer protection law, not a property law.
I'm pretty sure that falls more under fraud than it falls under trademark violation.
