> Another part is trademark law. It should not be possible for e.g. coca cola to make Pepsi cans with horrible tasting drinks inside.
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.
