That's great, that you learned a lot from those who had more time than 250 hours. I also learned a great deal from my primary instructor who was an ATP-ME, Gulfstream and Lear type rated corporate pilot who flight instructed on the side. But I also learned a great deal from my instrument, commercial, and CFI instructor(s).
But - anyway - not the point of this reply.
So what about the guy who is moving into a market that lacks an MEI, and he sees a great business opportunity to secure more clients - but - under your rules, since he only has 265 hours (he holds a CMEL, CSEL, IA, and CFI), he would have to wait until he has 1000 hours to get his MEI. . .thus. . .losing a great deal of income potential because of your little rule restricting the earning of a certificate to a certain TT hour requirement.
You see the holes in your positions now?
If you don't like the FAA standards, then lobby to get them changed. . .AOPA right? Or EAA? Or some other lobbying element. . .or. . .create your own if you feel so strongly about it.
