People make the argument that because only a few people at a certain time know a certain pattern that it is therefore "scarce." But this is treating a thought like a physical item. A motorcycle can only be ridden by one person at a time. But there is no limit to the number of individuals that can simultaneously use a thought. IP suggests that because someone had an original thought that they can become controllers of that thought in the minds of other people.
taking the motorcycle from someone who is riding it prevents them from using it. But using a thought that someone else had does not prevent them from using the same thought. It has increased supply of the thought. The idea exists in concept apart from the person who holds it in their brain and is available to anyone with a brain at any time. Some people would call the process of spreading thoughts and ideas "LEARNING." IP prevents sharing of ideas, collaboration and learning by granting monopoly rights over thoughts and ideas that limit the way others can use those thoughts and ideas.
