I can't see this being a huge problem? The bots won't earn money any faster, and marketboard tax will mean that selling cross-world will deduct a portion of that money from them with each transaction. (Unless they fail to make, say, Limsa@Typhon not detectably a different location to Limsa@Tonberry... but there are still seller fees draining some of the money, just not the buyer fees at the other end.)
Anyway, I'm looking forward to the legal version of this: being able to pass money from my main character to my perpetually-poor alts.
