Consider also. How big does the ship have to be? Is it detectable on entering or exiting? Can it be made comfortably non-detectable?
Imagine your hometown is located over 100 miles from the nearest other town of equivalent size and variety? So, with little competition, they institute rather heavy sales taxes. No competition from other towns, and all those social programs the city elders want, but few actually would value enough to pay for, (golf course for instance.)
Or, they institute blue laws, confident people won't go elsewhere for beer on Sunday, as there isn't any other place to buy anything beyond the edge of town.
Now, with sudden access to any town, anywhere, how much sales tax revenue can the town expect? People just pile in their car, still in the garage, and teleport away to another town to do their shopping. Sunday? They teleport to another town for the things that can't be had on Sunday at home.
It democratizes that which geography has made a practical oligarchy. If a town wants to survive, it must now compete in prices, selection, and regulations, with every other town, anywhere else.
This goes for governments too. A government can tell you what you may have, and how you may use it because it is at least impractical to go to another country for even an afternoon exemption. You can't have a gun? No government can prevent you from teleporting to the belt to buy one. Goes for anything else. People can actually live ON EARTH and ignore the government, as they go beyond the governments area of control to do their shopping. Once this happens, the government, seeing their regulations completely unenforceable, (and no stigma associateable with ignoring the regulations,) they either roll back their restrictions and taxes or lose MARKET SHARE to competing governments.
People may actually not leave. Just commute to where the government has no control. As they continue to commute, the government would actually LOSE effective control closer to home, either voluntarily to hang on to more of it longer, or by default as people decide to just make the move.
The story stated how you couldn't get a fusion reactor for "love or money" on earth, unless you're part of the elite, but they're a regular consumer product on Mars. If the earthers could teleport to mars for a shopping excursion, what is to prevent them from buying a reactor anyway, and grey-market wiring it into their house? Or, even moving to mars, where the things are legal and common, and commuting to earth for work, until the boss decides to relocate to the more business friendly environs of mars?
