More accurately: Intellectual property is about someone having ownership over information, as a photo for example isn’t an idea.

Remove it and you can’t retaliate against anyone buying or selling access to your company’s source code thus making it impossible to keep private. So all such source code ends up public at any reasonably large company effectively killing all AI startups etc. The same is true of any proprietary information thus quickly killing nvidia, AMD, etc. Medical R&D also dies outside of governments and non profits. It’s shocking just how many industries get gutted as there’s far less incentive to make accurate maps when anyone can copy them.

But hey, I respect your stance here.

PS: If you think contracts/DRM/whatever that’s the solution! Now you do have protection for info and thus IP again.
