This is bovine waste. Have you ever tried to get things bought from different locations? It is utterly annoying having to fly to 10 different systems to buy something. The point of Amarr and Jita is that you can buy everything there without hassle, not to accommodate gankers.
If you want to put trade back in all of high sec, I have a better suggestion: Start seeding stations/citadels outside of Jita with things. Make a fortune doing so and when you are successful, other people will follow. You can start breaking Jita up on your own, other people will follow if you put some thought and muscle behind your effort. There is absolutely no tax necessary to facilitate this.
You call yourself a Tripple [sic] A developer? EA or Activision, I guess? Only those would introduce something that makes the game a whole lot more tedious for no good reason.
