Maybe you don't like my phrasing? But fundamentally, intellectual property is a form of property that includes intangible things. How can intangible things be owned? Intangible things aren't scarce.
> Software isn't an idea. It required real work of a scarce-ish resource (software dev time) to create that software. You could make the argument that software, unlike a physical good, can be copied at almost no cost after creation
It's not about the work required to create it or even the work required to copy it. The point is that it's not scarce. That is, I can use a copy of the software without inhibiting your simultaneous use of it. This is a fundamental difference from a physical good. My use of a physical good inherently inhibits your use. This creates conflict and property is a vehicle for resolving that conflict peacefully.
> I'd like to put forward the argument that software _patents_ are the IP that most closely resembles the IP the author seems to hate
I undoubtedly hate software patents. But I probably hate patents in the healthcare industry even more, because I perceive them as probably causing even more harm than software patents.
My article is just biased towards issues in software because that's what I have the most experience with.
