You're forgetting some detail in your example, which is that
1. the existing STORES also sell almost all the CARS, and the GPS in these cars is hardcoded to only drive to one of their STORES
2. The government is considering a law that forces everyone to show their ID to open the door and drive their CAR,
3. To enfore #2, the government is considering a law to prevent drivers from manually entering GPS coordinates to any other stores, because the two existing STORES promise to enforce the ID-verification system in their parking lots.
Now you want to sell your HAT, good luck, because anybody trying to open up a Hat-Droid store with your product in it, is soon legally prevented from doing so. For security purposes. Think of the children!
