This situation is in no way unique to food trucks though. I could buy the property next to your restaurant and make it into an exact clone of your place and give away all my food for free until you're out of business. And yet I don't see anyone out there arguing in favor of laws banning copycat restaurants. If I can run a food truck and sell food at a lower cost to people who have to stand outside while they eat, and they prefer that over the experience you provide in your restaurant, the customer is not wrong. Good restaurants, by definition do not go out of business.
