> relicensing IP is not "using" the IP to me - you either use it, or lose it. Unless of course, you're the original author (and by author, I mean the humans, not businesses that paid them)
If I come up with a brilliant new compression algorithm, but don't have the software development skills to make a robust production implementation, what difference does it make whether I hire someone to write that production implementation, license my algorithm to someone who writes that production implementation, or sell my patent rights to someone who writes that production implementation (or licenses my algorithm to someone else who does that)? Heck, given that software is fluffy abstract stuff rather than physical goods, would you consider selling a program to count, or is it only someone who makes a hardware device that uses the algorithm who gets to count?
1) You patent something, but don't do anything with it except enforce the patent.
2) You patent something, but the only thing you do with it is license others to use it, potentially hiring someone else to manage the licenses but you retain ownership.
3) You patent something, you sell the patent to someone else to do 2)
Cases 1 and 3 have significant negative effects on both technology and society that the law should prevent. Case 2 covers your brilliant new invention but don't bring it to market yourself and is fine.
The key notion here is that you cannot sell intellectual property. It's ephemeral. You can license it and create all sorts of creative license terms, but once you're dead or the timeline of exclusive rights runs out, or you personally stop "using" it (or all companies stop using it), the patent effectively expires because you can't claim damages if you or your license holders have not seen any negative impacts.
In a perfect world, "defensive" patent strategies and rent-seeking by middlemen would be prevented by construction. This maximizes the incentive to innovate and share ideas, instead of bottling them up. If you want true, exclusive rights to something, don't share it in a patent.

How are 2 and 3 meaningfully different as far as anyone outside is concerned though? If I own a field and I'm not a farmer, no-one cares much whether I rent it out to someone else to farm on or sell it to (either for some proportion of their income or for a straight up flat fee). Economically it's all the same - you can rent something or you can buy it funded with a loan, and your cash flows will be more or less identical.
