Yes, some licenses have poorly defined metrics that are hard to properly evaluate.

No, ensuring people that claim to understand a topic they are selling their advice on as a product actually know what they are talking about is not a worthless endeavor.

Should a Doctor have to spend a certain amount of time performing operations even if they nail their first one? Should a pilot need to fly 50 hours in a circle even if he got his landings down in the first 3? What if a person can pass a law school final the day after they take the LSAT? Should they be able just to skip law school completely and be admitted to the Bar? Clearly law school only exists to discourage employment!

I'm constantly amazed at how so many of the people that don't think time invested matters at all never have time invested themselves.
