You keep refuting points I'm not making.
Regarding your book suggestion, if the book is full of good examples, it shouldn't be hard to provide me with one instead of asking me to devote the time to read hundreds of pages. Not that I might not get to this book at some point, but I don't think asking the other side to go read this or that book is a fair thing to do as part of a discussion.
For instance, some hold that it is not even property, since two people can have the same idea, and not infringe on the other's right to do so.
I'm not aware of jurisdictions where ideas themselves can be copyrighted. What gets protected by patents or authorship laws are particular implementations. As far as I know in most jurisdictions, if you can prove that you had no knowledge of the patent and you came up with something similar on your own and can demonstrate that, the patent is not enforcible against you.
Sure, there are a lot of questions to be had about IP and patent laws, but if you throw them away completely, you get a lot of industries going under too, so it's always a give or take. The idea behind patents as a whole is to stimulate innovation.
You'll thank me later

I doubt the book has convincing arguments if you are having a hard time summarizing them...
I did summarize it. You asked for examples, i provided a link.
Hoping that if you don't believe me, maybe you will hear out other smart people; )
