Why do people always demand strict licenses and mandatory insurance for everything? Scooters, bicycles, small drones. What's next? Need a license for the paper airplane you made because it might poke out someone's eye? Human bodies are big and heavy - they can do a lot of damage if "used improperly" - should we require a license and mandatory insurance to go outside into public spaces too?

A license requirement for a car makes sense - you're dealing with forces well beyond the norm for what a human body has. Small drones though? I just don't see it.
