I would think that their insurance carrier would expect the FBO to have some
system in place to assure that the people they rent to are legal and
qualified to fly the aircraft that are being rented.

Agreed. The question is how intrusive that system ought to be. It
would be simple to subvert anything that's not intrusive. OTOH I've run
into places that want a copy of my driver license, pilot certificate,
medical certificate, logbook, and my SSN before renting.
