Under the current law: NO!
That is just a dream from the people that are pro-IP -- they know, that is a dream, but they want you to dream it.
If you are working for a company and have an idea, the company gets the patent and you get (if you are lucky) a fixed amount (~$500 is a typical amount in my country) and the patent belongs to the company -- you don't even have the right to use the stuff for yourself.
IP means, in its conclusion, that the creators are disowned and the "owners" own your ideas. You created it, you are busted!
I guess, you are.
When you still find an employer, that makes a contract like that, call yourself lucky. In my country, it is a law -- and you can't cancel out laws in my country in contracts.
Not everybody is so lucky, that he has enough money or finds fitting freelancer work.
Ask the music people. They (oftentimes) can't sell their music without having contracts with big companies -- and they have to sell out all their rights.
But it seems that you just view the world from your standpoint -- fading out any negatives -- and everybody that has different experiences as you do, is just stupid or "obtuse" in your view. With such an attitude on your side, a discussion makes little to no sense.
If creative output has a value, then people should be free to exchange their creations for anything they like. To create restrictions that prevent people from writing a book then making an arrangement with a publisher, is just to prevent people from actually being able to do anything with their creations.
