A private company couldn't write tickets, and likely couldn't discriminate against private cars that just happen to be hired (but otherwise indistinguishable from the private cars delivering other customers). SFO has been granted a monopoly on land, waterfront, and airspace by several levels of government, and is owned by the public, so this reductionist "the owner can do as they damn well please, social welfare be damned" analysis doesn't apply.
