How did you arrive at that conclusion?

From the fact that this is how it works now.

The GA airports that I fly out of
have "commercial airline services" of the type that I've described, above.
They are _charter services_, corporate and coop services, all of which are
flying under Part 135.

That's not quite the same as an American Airlines, though. The market
is different, the volumes are smaller, etc.

It is precisely their difference from the
necessities of large carriers that make them viable, and part of that
viability is the far greater number of airports that can accommodate them.

So it's not clear that a change would be for the better.
