What usually happens, is that you take what already exists and build on top of it. Without being able to do that, you'll have to not only recreate that technology from scratch, but you also need to make it different enough so it's not similar to the patented technology.

Overall, for the world, it's much better to be able to use prior knowledge without much or any restrictions, the way humanity has always evolved before patents or copyright even existed.
