I think it all comes down to what you want from flying. IO540 (seems to be) an intensive business flyer with a very nice GA a/c and there is a place for that. On the other hand there are people like me who just like flying and are happy in a spam can/glider and love chewing the fat with other flyers.
I can see why 540 wants a hangar and good runways/facilities, but of course I don't need those and I suspect most people here don't. Let's face it, other than the few business users/pro pilots here, it's a lot more sensible and cost effective to drive wherever you are going.
We fly because we love flying and we put up with the crap in this country because we need to fly.
I might add that I fly from an airfield with ILS and ATC and don't pay anything for circuits and landings so perhaps I'm a little spoiled.
