Would I be correct in suggesting that it's easier for the task force to identify Gil buyers the more Gil they're buying? Because if it's easier to identify someone who just purchased 20,000,000 Gil and than it is to identify someone who just purchased 200,000 Gil, I'd say the high prices still act as a fairly good deterrent. At the very least, it's an easier way for them to remove RMT Gil from circulation; If someone buys 2,000,000 Gil and buys lots of items off the Market Board, that Gil has mixed with plenty of other players and they can't really remove it easily (the last time they did, there was a massive uproar). If someone buys 2,000,000 Gil and buys a plot of land, that Gil is gone and when they're banned that plot is free again.
