Tell us again why anyone chooses to fly here?

Blame the FAA for that. Originally, their landing fees exempted light
aircraft. They wanted to limit the heavy/loud jets because of
neighborhood complaints. When the jet types cried "No Fair!" the FAA
agreed and told SMO that if they were going to have a fee, it must touch
everybody.
