Katamarino, I wouldn't pay too much heed. Indeed, look up SoCal App's post history.
You'll soon see that EVERYBODY is a troll in his eyes!
SoCaL,
If you honestly think an FBO is going to rent one of their aircraft for the purpose of such a trip to somebody who has no experience of such flying is probably dilusional - or has a sufficiently large bank balance.
Why not? That's what insurance is for.
If the insurance does not cover the planned expedition, then fair enough. PERSONALLY I would pursue it further and put questions forward - "What would be the excess premium IF...?" etc, but for the purpose of this thread, FAIR ENOUGH.
If the insurance DOES cover it... No reason to disallow it. If I knew my car was fully insured for the purpose and I would redeem the full value in any problematic/disastrous event, I'd happily let someone rent it and try to drive it across the Atlantic! I'd get about 5 hrs worth of rental income before the inevitable happened!
As to the MORAL issues, well, a different kettle of fish.
