That is like asking how could linux exist. Use your brain and imagine. We would likely have many more great fonts than we do today if you outlawed charging for them because people would no long have a protectionist mindset. It would be easy for people to modify existing ones so they worked better for various issues, and it wouldn't stop people creating beautiful new ones for whatever reason they wanted like art... or like linux. Sometimes the world works better without capitalism though that might be hard to believe.
