I agree. The airspace is for everyone, if they know how to use it. It goes back to the slow driver in the fast lane. YOu can drive slow in the fast lane all you want legally, but it's not courteous. You are slowing down aircraft that burn more fuel a minute, than you do an hour. Example, I flew with one of my instr. students to Palomar one day. I was cleared for the appr, but had a citation right behind me. I was holding 110 in a cherokee on my own behalf, trying to give the guy room. Legally, it was my approach and my airport. I got there before him! But as a courtesy, since it was vfr, I cancelled IFR, and turned out to let him in. The guy would have burned more fuel going missed, than I did in my last 2 hrs of flight.
On the other hand, I take students into LAX,ONT,BUR,and SNA on almost a daily basis. To say that some regional or airline pilot "lets me by" is a joke. I filed same as you. I wait for a release same as you. I fly as fast as I can on an approach to help you out. You WILL wait behind me for release! The last I checked, the FAR/AIM doesn't care if you are a 74 or 152.
What's my point? Everyone has a right in the busiest airspace if .................... you show enough knowledge and courtesy to know that the other a/c around you are faster, cost more to operate, and can't always slow like you can..........blah, my 2 cents worth
