Which leads to my next and probably most serious question, what is to stop gil sellers from controlling both markets? Buying up bands and selling gil to make up the cost but still be able to eek out a profit from it?
...

The number of bands that can be bought off the mogstation is infinite. RMT cannot imagine to about of RL money they need to do this. And furthermore what is a RMT seller going to do with all the bands anyways? Are they going to be able to sell them for more that the Mogstation? Who are the consumers clueless enough to consistently and repeatedly overpay for the stuff that is easy to get from the mogstation. So failing that, are they going to sell them at a loss over and over? RMT gil seller are not insane like players can potentially be, because they are in it for the RL money. So what this means is the RMT gil sellars can not and will not try to mess these wedding bands.

Does it mean some of the RMT with money and guts won't risk a few bucks to play the markets while the pricing discrepancy are working in their favor? Obviously the chance exist that some them might have made a windfall of gil that they now have to figure out how to unload, but it may more may not work out in their favor because they will have to deal with compete non RMT players sellling band and getting gil and reduced demand for the gil seller gil. Remember RMT wants dollars not gil, having more gil means more work to sell that gil, more risk, and if they put in dollars to get gil, that also increases their risk. And holding on to hundreds of dollars worth of wedding bands when the wedding rush is over, is having lots of loss making inventory.
