First off, thanks for paragraphs!
Second, I wouldn’t recommend trying to email Kinsella. He’s pretty busy, and he’s basically dedicated a large portion of his professional life publishing and popularizing material to tackle this question…so it would be much more tactful to simply read the resources yourself.
Luckily for you, patents are in my opinion actually an easier case to argue than copyright. Indeed, even people who insufferably argue in favor of “IP” sometimes admit patents are overused and even should be abolished.
You can get an enormous amount of resources from Kinsella’s archives. See the links here (in particular his Mises blog archive and resources at C4SIF.org)
Also check his lectures here. This one is quite good. And interestingly enough, the topic of “science as a public good” was recently brought up here. Definitely check out Kealey’s lecture.
And obviously do a search on the main mises.org page for the word “patent”.
To see a real world case study, showcasing the problem with patents in the very field you’re talking about, in this thread (where this topic of medicine was brought up) I mentioned a great documentary on Australian television that covered this very issue, called Patently a Problem. Check out the links there.
