I wonder after this if focusing on gas stations is worth it anymore, after a long time the gas stations will become unprofitable to operate, sure you can move, but moving every 3 months can be very annoying. But yes raise the gas prices and have less people buying gas, but the problem with this is gas stations near large asteroid field will benefit greatly since more people will come here since there will probably cheaper gas prices. Yes this creates competition, but I m restating my earlier point to what cost. Have large wars over some large asteroid field just to be able to have a cheap and affordable gas station there, sure but you could possibly waste more trying to defend it than earn profits from it. Sure move gas stations every time and your other gas station is useless since no one wants to buy from it. I know there is trillions of asteroids but trying to fight over each one will waste them pretty quickly. Hope someone will have a solution to not raise prices to almost unaffordable buying from it and not having to keep moving where your gas stations are located.
The less gas there is locally, the more valuable your gas station is as long as someone needs to use it to get somewhere they're going. Fuel, as is the case with most commodities in MMO economies doesn't generally require much in the way of persistant infrastructure. The initial boom of nearby rich deposits ends up bankrolling your setup and from that point its just refining and efficient pilot management. You assign mining ships to the most priftable mining sites and hauling ships to distribute because that gas is pretty much linearly worth more the further away it is from a source of gas.
This is precisely how the IRL oil market works. Most of the world's vehicles run on fuel that is refines near a deposit and then shipped extremely long distances. As long as there is a persistant need for fuel, and a generally understood average travel distance those gas stops are going to find it very hard to be unprofitable.
Sure, on a long enough time scale you might find a station worth abandoning because its not on "the highway" any more, but for the most part if you're doing your job right you've made enough money on it you can afford to abandon it for greener pastures.
That's far preferable to an econ game where the first person to stake claim to a persistant moon is essentially set up for life as it creates opportunities for a combination of prospecting and pvp to control resources rather than pvp alone being the sole determiner of economic power.
