An airport authority cannot limit access to the airport for "private"
instructors running their own operations and not being associated with a
"recognized" flight school.

To do so they would jeopardize their Federal Funding.

This has come up before, and although you are correct about them not being
able to stop you from teaching at a publicly funded airport, they can
require you to do other things, such as establish an office at the airport,
and to rent the office, and possibly hangar space from the airport
authority.

They can not keep you from flying in from elsewhere to practice, so it might
be a good idea to find a place that will not keep you from teaching as you
wish.
