Removal of IP here means that you've enforced a penalty against innovators and creators, and baked incentives for grifting and leeching straight into the system. The system we have right now is flawed, but the remove all IP argument is even worse.
I'll also pre-empt the "But research is government funded" side tangent, getting the drug from a proof of concept/academic study to something that can actually be used is horrendously expensive, and this bit is completely in the domain of private industry. And if you think academia is going to replace that in this no-IP world, you might want to look into how the academia -> industry pipeline actually works.
On a more software side angle, I've found it interesting that the biggest anti-IP people I know also bemoan the general move over to SaaS.
