I'm not sure about his prediction, but intellectual property does highlight more than most other issues the split between the individual-rights/libertarian version of capitalism, and corporate/pro-business version of capitalism. Intellectual property requires a particularly high level of intrusive government policing; for example, it can be illegal to copy a book by typing it on a typewriter in your own house, where you own the land, house, typewriter, and paper. It's definitely illegal to screen someone else's film for payment, even if the entire transaction happens in your living room (you project the film, in your house, using your own projector, to people who pay you in cash inside your house).

This sits very poorly with the government-out-of-my-house-and-off-my-land version of libertarianism, since it inherently requires agreeing that it's the rightful role of government to police what you do in your own living room. It feels more like social engineering than anything libertarian: the government has decided that, in order to promote the good of society (encourage artistic production, technical innovation, etc.), it must police what you do on your land.
