Well, the nose of the camel is having the gummint require us to check
in with ATC on every flight (and pay their fees) as is common in some
european countries...

As far as me personally, ATC could vanish and it would affect me very
little - and that 'little' could be worked around... I file IFR less
and less... When I do not file IFR I do not need ATC...
I can, do, and have, flown from one border of this country to the
other without talking to ATC...
Without ATC, if the weather is IFR I would have to lay over until it
improves... That would affect roughly 10% of my trips... From my
point of view an acceptable price for having the gummint off my
back...
