Man, you don't know what is porpouse of "busines" ? Generate profit.
And yeah, upkeeping PoB takes some time and effort, so thouse players are limited with standart traditional cargo from A to B trading, so they compensating it with such equipment trading, why not.
With 5Ker, even being hard core RP trader (haul only thouse commoduties, which your NPC's faction base selling, or purchasing+ Planets which are for everyone), so generating 200 millions isn't challenge at all.
