You stated the wealthy business men could taxi to their hangars attached to their homes. Well since most business jets are crewed by professional pilots, where are you going to have crew accommodations? I'm pretty sure the boss doesn't want the hired help living it up in the same house. Also with all of these attached hangars, have you thought about apu and takeoff noise? I doubt if a guy has enough cash to afford his own jet that has the range to whisk him to a tropical island, will want to listen to all of his neighbors' airplanes. There are plenty of other concerns for your development but these are two examples of what you will run up against.
