This is a good sentiment but wrong idea. The natural state of the world is everyone copies everything. This is hugely beneficial once something is discovered/created. Copyright harms everyone after the fact because of this. Before the fact, credibly limiting copying (i.e. copyrights/patents) may increase discovery/creation. That makes the correct question what is the minimum copyright/patent to get the most increased output for the least cost in lost copying? The answer is a small fraction of current copyright, almost certainly. so there are many decades where fair use now matters when it shouldnt because no copyright should exist at the time fair use is contemplated
