I support, in principle, the concept of IP, and the right of IP holders to enforce their rights, and I hope everyone else on Hacker News does too.

The big questions aren't "should IP even exist as a concept", but instead "how limited IP should be", "what rights IP ownership should give", and "what avenues are available to enforce those rights".

Don't forget, "IP protection" is a really broad concept, and it's more than just patent trolls and DMCA takedowns issued by corporations on content they don't even control: It also includes, for example, the ability to release code under your open source license of choice and then see it enforced through the courts.
