In my case it's more to do with cowardice. I've been around long enough to get seriously worried when flying in areas that I know may be populated with people who feel that have precedence over others, when legally they don't (as far as I can see).
This is the best argument I have seen for the mandatory imposition of controlled airspace around every instrument approach.
We have a direct conflict of interest in GA between those who quote the fact that Class G is uncontrolled so they may do what they want and to hell with ATC, and those who look at a map, see a marked approach and consider avoiding it (or at least talk to ATC).
As far as I can see the forthcoming change to ATSOCAS will do nothing but make the situation worse.
