I don't think most people on HN even believe in intellectual property conceptually, much less view their activities through that lens.
I develop software, and that software has a license (mostly AGPLv3 at this point) because I live in the real world. But it's nobody's property; it's just math.
Yes, companies exist in the real world. The real world is full of open source. And full of companies that produce open source material and don't regard it as "intellectual property" except insofar as to license it to protect themselves and their users/readers/customers.
Presumably you think copyright infringement is theft too.
The problem IP laws try to solve is that the best researcher is not necessarily in the best position to execute on their discoveries. Or, worse, executing on the discovery is incredibly cheap (such as new drugs) and the value is impossible to recover. The more expensive the research, the more likely that is to be.
Research either needs to be publically funded OR some kind of limited monopoly applied.
None of this implies that the current IP mechanisms are not seriously broken.
Oh, best just stay thirsty then.
Hang on, perhaps I can force the people to pay for security guards that stop them from using my bucket ...
