People buy hardware, software, services all the time.
There is a big difference between hardware and services, and patents. Software is a whole other deal, and I object to the whole model of proprietary distribution as well, but that's besides the point.
Fact is, an idea is an abstract concept, not a physical good or a services. One cannot own an abstract concept - the very notion of that is completely nonsensical. If somebody has a an idea, and tells (gives) that idea to somebody else, both people will have that idea now. You cannot say the same of a physical good or a service.
Besides, arguing for the status quo by citing the status quo is a circular argument.
the idea to just throw it all in the trash bin is a bit black and white.
We have a system built upon paradoxical, nonsensical and self-contradictory basics which does nothing but help create artificial monopolies and slow down or halt technological progress for the benefit of a few big corporations.
There is but this only option, and that's to completely scrap it and never try it again. I'm honestly tired of seeing 'but that's black and white thinking' in defense of a completely indefensible position. Sometimes there are things which are simply bad - patents are one of those things.
You could for example have (international?) patent courts that
would prevent monopoly-by-patent things.
The solution to a massively broken system that, in large parts, relies on huge amounts of bureaucracy is even
more bureaucracy? I think not.
You cannot fix this system - it's broken by default.
