It could give the bots far better selling power, especially since bots are only banned in waves.

For example, a bot establishes on Zodiark and lists a few thousand potions and food at ridiculously low prices. It gets known around within a few days that Zodiark is the place to go to stock up on raid consumables. The bot now has the entire data centre as their market and can make a ton of gil before the next banwave. Banwave hits, bot establishes on a new realm, rinse and repeat.

Meanwhile, everyone else on the data centre selling consumables legitimatly is affected.

Bots have been rampant lately, even moving onto endgame gear markets. Considering the issues Enix have in handling them, I'm baffled why they'd offer them such an advantage.
