My impression is that it's pretty easy to get a Part 107 Remote Pilot license; I think it's essentially just a knowledge test. Even if all you learn getting it is how the airspace system works and how to coordinate your use of it, that's a significant base of knowledge that is essential to flying responsibly in the US. There are serious civil and criminal penalties in the Federal Aviation Regulations for lots of complex rules that really do matter, so it makes sense that they at least just want commercial operators to understand what they are on the hook for.
