My only interest is safety, period.
I'm not justifying anything, taxes the least.
If you think that you can do without ATC, so be it.
I know from experience that mixed traffic (IFR and unknown VFR) can be a dangerous thing (As I've described above).
It is not about restricting VFR flights, but in certain areas, I want to know what they're doing and what their intentions are, to their benefit as well.
BTW "reasonably safe" is not safe enough...
