LostThePicture - well named!
You're wrong in almost every important respect.
Just about nobody (CAA, NATS, MoD, civil operators) think the airspace we have is fine. And it needs rather a lot more than just "certain civilian carriers to use it properly", although it does need that.
It also needs certain (minority) military elements to show a sense of professionalism rather than yeeeeha gungho-ism.
Basically, I get the impression that you've never seen the world from the flight deck of a regional airliner, nor have any idea of what goes on in civilian aviation except for what you see on your screen. Please confirm this is wrong?
