Do you inspect the license of the person who cuts your hair every time you get a haircut?

No, you don't.

How do you know what I do? Admittedly, it doesn't happen very often, but you can bet your butt I'll at least take a cursory glance at a barber's licence before I trust him/her with giving me a straight-razor shave.

I can print one off in 5 minutes.
