Your logic and reasoning seems limited at best. A school doesn't want a flow of visitors; Gatwick sure as hell doesn't want a bunch of small private aircraft; but if you're willing to pay a silly/punitive price both will accommodate.
Conversely, a hotel with a restaurant does indeed wish to have visitors.
Exactly my logic. A hotel with a restaurant doesn't exactly need to have HELICOPTER visitors. And if they do, maybe they don't need to have CHEAP helicopter visitors, and seem to find that on the supply and demand curve, they succeed by charging a landing fee and get the type of visitors who spend and tip well.
