That argument is about as valuable as "think of the children."
> Do you feel drivers should have to get a drivers licenses?
That's not the right analogy. The equivalent would be requiring special licenses for all car dealership employees, which is not required. Salespeople aren't themselves doing anything medical and there's no reason they should have additional requirements beyond normal salespeople. We already have laws covering both (a) fraud, (b) minimum requirements of healthcare plans.
> A simple health example off the top of my head
Existing consumer protection laws would cover this. You can't sell a product and claim it has a feature which it doesn't — that's fraud.
Nothing about health insurance should mean that salespeople should require licensing. It's pure rent-seeking. There are plenty of other dangerous things which are sold by salespeople without licenses.
