The get a crash course in why cities started to regulate Taxi service check out a Cagney film, The Roaring Twenties.

It can get ugly out there on the streets when there is lots of money involved.

Anyone could run a Taxi service back then. Of course anyone could also meet with an 'accident' if they tried to go it alone. When the Mob found out how easy it was to squeeze individual drivers cities stepped in to regulate the business in the hopes of driving out the crime bosses.

But that was then and this is now and times have changed. When you start building your own airports you can start making your own rules. Just make sure your place is so remote no other aircraft ever come into the area since they are like cars on the highway and follow the rules of the road.

You are also free to build your own highway. All it takes is money.
