What is a patent? A patent is the government incentivizing innovation by encouraging inventors. It does this by spending people’s freedom — it gives the inventor the right to prevent other people from making or using that invention for a period of time.
Similarly, the government spends people’s money to make a highway. You want the government to make highways. But if the government is spending $20 billion per kilometer of highway, you might say, “Wait a second. I want you to spend some, but not too much.” When highways cost too much — when one kilometer costs $17 million to develop — it’s almost always associated with mafias and corruption. To bring it back to patents, how can there be a kilometer of innovation that costs all of people’s freedom to develop? There must be corruption involved.
