Protect people! Ha! The laws covering cabs require them to go into undesirable areas so those that can't afford a full car can still get around, accept cash payments for those unable to get credit, vehicle inspections, and so on. When you say protect people, do you just mean the people in your bubble where everyone has a card?

Taxis in many cities will refuse to go somewhere (e.g. JFK, South London, outer Beijing, ...) even though they are legally obligated to take you anywhere. There is little recourse. The driver's medallion won't be taken away for breaking the conditions of the monopoly.
