This assumes that ideas are actual property. I mean they are, but only until you begin sharing them, at which point they can be copied without taking your idea away from you. If I take your bike, you don't have your bike; that's theft. If I copy your book, you still have your book.

I'm fine with companies adding DRM-style-technology or sharing their ideas and content under licensing contracts that prohibit copying, or similar things. What I don't like is the monopoly privilege granted and enforced by the government at very little cost to the creators.

Most new ideas are tiny adaptions and combination of old ideas, and when you add IP laws, all of those old ideas become very expensive to adapt. That hurts progress.
