Perhaps the first privilege should thus be re-stated as:
To fly IMC/IFR in permitted airspace.
I think that would be much more acceptable in a European context.
It would allow individual countries to not classify any airspace as permitted if they didn't want to.
It might also allow sceptical countries to start off with just class G being permitted, and they may get more used to the idea as time goes on and start adding other classes.
