I will definitely check it out and take it from there. I still don't feel like I have all the information I need, so I reserve my judgement until then.
For now I'd say: People all over the world spend money on what others consider a "stupid hobby" and that includes paying for expensive collectibles, Comic books, Tiffany lamps, porcelain dolls...hell, think of anything crazy and outrageous and ppl will collect it and pay money for it. Lots of it has no value - but for the collector. So what is so bad about a RMAH in a game? People pay for items in F2P games, people pay for items in WoW. People pay for bloody RINGTONES ^^
Just another facette.
