I am not talking about a person who has his own plane and rents it out once
in a while - rather a person with one more who owns them primarily as a
business proposition. So how is the individual owner's insurance more than
the FBO and how is that going to make it more expensive?

In order to insure for flight instruction use (other than the owner/named insured)
generally triples the insurance cost. Doesn't make any difference if it only gets
rented once a week or in every two hour block all week long.
