Plain and simple, if you have large amounts of potentially counterfeit money prepare to have possible action on your account. Even if it is just the suspension of said funds there may still be action. You can complain about it but the realistic thing about said funds is that they are earned illegally and thus forfeit to the government "SE" when they are found. The best options at the moment are A.) If you truly feel they are worth that amount halt sales until people can legally earn that kind of money. Only the crafters have the money to buy things obscenely priced. B.) Lower the price to something reasonable so that people will not feel the need to buy gil to afford said items. C.) Stop playing if you feel the need.

I am not trying to be mean, rude, or inconsiderate. Personally I stopped crafting after I made gear for myself and friends as I felt this situation coming and I did not want to invest the time and effort to undercut the market and then be looked at oddly by the Special Task Force.
