Fedex lost a caravan to this very thing a number of years ago. No matter how full proof you make something, there is always a way to defeat it.
As far as using the seat belt as a gust lock, on some airplanes, that's the only way to keep them from flopping around as they weren't designed with a gust lock in mind.
Of course there will always be pilots that circumvent such devices, that's called a deliberate irresponsible act, something beyond the makers intentions! I never use my seatbelt, it can get damaged as they are not designed for anything other than holding a person. I have a long length of "hook&Loop" strap that I wrap around the control stick and secure it to the seat frame.
