"The Obama administration often describes TPP as the most progressive free-trade deal in history" Does anyone see stronger government enforced monopolies (patents) as the opposite of free trade?
All property is a government enforced monopoly. Without property there is no trade. There is no reason to transact when you can just take or copy.
For instance, I have a leatherman "Micra" in my pocket. It's my property. I can tell I still own it by putting my hand in my pocket... yep, it's still mine.
Now, "intellectual property" is another matter all together. I can't tell is my "intellectual property" is being infringed on without a large effort to police it. Is my fantastic new way of rigging sails being infringed upon by some "pirate" on Lake Michigan? I can't tell. My sailboat still have the fantastic new way of rigging, so I'm fat dumb and happy. I have to have a state, or some huge organization, find the infringement for me.
I think that's one difference in property theft vs "intellectual property" infringement. I'm not exactly sure what to call it, other than "government enforced monopoly". Yes, some laws around property need to be in place, and governments need to enforce them. There's a difference in both magnitude of enforcement, and type of enforcement that's necessary for "intellectual property" to exist.
As far as "just copy", well, I'm using my capital (expensive computer) to manufacture those copies myself, should I actually do that. The enforcers now need to keep me from using my capital in a way that I control. That's another significant difference you're glossing over.
