Except I think SE's intent is to try to equalize MB prices between the worlds over the long term. They're less concerned about individual world economies and more concerned the the game economy as a whole. Most competition tends to lead to lower prices overall even if that means a slight increase on some worlds.

They did state their initial intent was to have data center wide marketboards when they added World Visit but they hit technical snags that wouldn't allow them to implement them, and it's still something they want to accomplish.

What players forget is that when prices on certain items they want start increasing, they have the ability to go farm the items themselves. It creates not just the opportunity to get the item for personal use at no (or at least very low) cost, but to get the item to resell for profit.

Locking marketboards to world/data center visitors won't accomplish much when wealthy players can simply transfer their character to a world, buy up the low priced items, then transfer back to other worlds where those items sell for more. It becomes a new form of gil for real money. I doubt SE has the ability to make an item obtained on another world just disappear from a player's inventory. It would be disruptive for players who wish to change home worlds for other reasons.
