In my locality, in the last 10 years we have gained one golf course and lost one airfield, (not in the same place). The airfields that remain don't look much different to 10 years ago, just a little more run down. The other golf courses all look a bit nicer, despite 8 years of drought. I don't know that golf courses are big money earners, but people seem to like to live near a golf course and don't seem to like being near an airfield.
Whether practical or efficient or sane, if enuf well-heeled punters stump up their $194k it can only be good for airports, even if they skimp on the parking for real aircraft:p
