Strict enforcement of patent laws ensures that capital will be invested in innovation.
If capital was allocated democratically rather than at the whim of companies (that end up chasing taxpayer subsidies anyways... SpaceX, Tesla, etc.) you wouldn't need to strictly enforce patent law. The risk is already being assumed mostly by the government for truly bleeding edge research. What we have in practice is a system where the cost is socialized and the benefit is privatized.
Considering most of my issues with patents is around trivial software patents and the abhorrent practice of slightly modifying a formula (coupled with paying generic manufacturers to not produce) to effectively extend the usable lifetime of a drug patent, if anything, it's the West that needs to change to make patents be actually good for innovation and not just a means to throttle competition.
I mean would fucking North Korea be a heaven of innovation if only they more strictly policed IP law??
