An airstrip / airport to me is like a road, a footpath, a beach, a river, an open space, a local hospital, a council run caravan park or a golf course
It is a public / community asset - it is not like McDonalds or KFC
It has a use for the betterment of society and the community. All members of the community will not use it - but, they might do at some time. Airports perform ambulance and search functions; etc etc. They can make the community safer. Thay can promote the community and some also say thay stimulate the local economy. They certainly provide employment
Aviaiton is an important part of 'time poor' lives. Airports are the grass roots of where the people in the pointy ends of airliners have come from
I think it is inappropraite to charge each individual that uses an airport an individual cost - it should be seen as a community cost
I'll predict that if 'user pays' continues to be applied to airports ............... they will be proved to be uneconomic - they will then close and then be occupied by buildings like houses, McDonalds or KFC .............. then, people will realise that more airports will have to be established because there 'aint enough of them
