That sentiment seems like a combination of communism (inventors' work is not his own, but belongs to the public) and wage slavery (one should not derive more than X dollars wage for Y hours of work instead of the true and unknown market value of the work).
The image people have of the lone inventor, toiling for years against the odds to perfect his concept, is just utterly wrong these days. Most patents are filed on behalf of corporations, and represent the work of teams of salaried employees, who in general will not see much if any direct personal benefit from the invention, beyond the odd bonus, or maybe, if they prove able to repeat the trick, a promotion. Where's your wage slavery now?
It's not communism to assert that a large part of the knowledge and skills that enable a person to come up with a new idea are the end product of centuries of shared human endeavour, and that therefore all ideas ultimately must become public property. What kind of a world would we have if everyone kept all their ideas to themselves, and every human interaction had to be a commercial transaction? Not one I'd want to live in.
You talk of the "true and unknown market value" of a patent -- I'll give you "unknown", for sure, because the state-granted monopoly of a patent exists to guarantee an artifical scarcity of the idea and results in the patent owner being able to extract a much higher "value" from the invention than a free market would provide.
You seem to be arguing on the side of the patent trolls who are the original topic of this discussion. You can't believe it's right that some a**hole, who was probably not even remotely involved in creating the idea, but happens to have acquired the rights to a dubious patent, should be able to live off of license fees and hold to ransom companies which need to make use of the idea to make real products and employ people, robbing them of the ability to make an honest living?
Also, who is going to compensate the inventors whose inventions are not commercially successful -- 90% patents don't make money.
The simple answer is that nobody owes anyone a living, so nobody's going to compensate people who come up with useless inventions. I hope you didn't think I was suggesting that "society" should fund the assorted crackpots and chancers who attempt to game the patent system.
