The point was only that some things can harm some people while helping others. That should be fairly uncontroversial. If you don't like the lemonade stand analogy then I'm sure you can tweak it a little so that it fits, instead of giving it away, selling it at a lower price or even the same price. I'm still hurting your business by not giving you the entire market to yourself. I'm sure you could come up with your own example if you gave it enough thought.

This leaves us with the real question regarding IP laws: are they a net benefit or a net harm to society? If you don't know one way or the other and can't provide evidence to backup your assertion then you have no business advocating the existence of such laws. One assumes that the state of nature is the default and that we don't keep laws on the books without good reason. I personally think that IP laws are a net harm because it stifles innovation, i.e. nobody can use the likeness of existing fictional characters to reinterpret them into new contexts and stories.
