Like golf courses, aerodromes take up a lot of acreage for relatively low density activity. Around here, we have lost three thriving aerodromes, with a fourth on the chopping block, yet I see more golf courses open. And those embedded in the city seem to remain and thrive. Yes, golf courses are less noisy that aerodromes, but perhaps more to the point is what I hear people are willing to pay to play golf!
The owner of the property may choose to exploit the greater value from their investment - that won't be aircraft use! Most of society don't really want an aerodrome, so make no effort to sustain one, and surely won't pay toward it! Who's left to pay - the users....
