If you are in IMC there is a full ICAO safe separation standard. When IMC exists it's equivalent to class A airspace.
If you are in VMC it's the existing system we have proven over 50 years plus the important safety feature of a zero extra cost NAS type Unicom that at a minimum confirms your radio is on the correct frequency and working correctly to increase the chance of alerted see and avoid working.
Bloggs you appear to be one of those pilots who is convinced you are superior and won't make errors similar to those that happened at Benalla that killed everyone on board.
And no doubt you would never dial up the wrong frequency!
We are not all as " top gun" as you believe you are.
