It's bad enough on the Marketboard seeing people undercut, I can't see why the bracelets will be any different. If someone wants to sell but there are no buyers, prices will have to drop until a buyer is found. Not only that, but as mentioned, RMTs will have no problem in competing for a better £/€/$ : Gil ratio because it's their job. Sure, SE could just lower the price, but why bother? People are going to buy it anyway to either sell on or for personal use.
On top of that, buying the gil over the bracelet leaves you still with the freedom to spend the gil on what you wish should there be any left over. Don't get me wrong though, I am not implying that everyone is buying from RMTs in order to purchase these via gil, but encouraging large sums of gil to be circulated around the economy....there's no way all of that gill will be legitimate. It's not even just the bracelet either, the new dyes are being sold too.
People want to get married but there's a lot of people that also want to make gil and make it easy. Only thing with selling the bracelet is that it is a "legitimate" method of making gil.
