Best-case end result of this is that bitcoin transforms from a vehicle of speculation to a vehicle of commerce. The classic problem with opening your own dot-com online store is visibility: who's going to buy your product if they don't know about your website? How do you break out of a local market? Where does your advertising money get spent? How do you connect with your audience? Ebay and Etsy etc somewhat solved this by providing a shopping mall type setup, where people interested in spending money are browsing products; you're much more likely to get search hits for "unicorn pendant" on ebay than you are on google. Suddenly you don't need to break through the non-commerce noise, which is overwhelming on public search engines.

And so you set up your shop in TMK and start selling the chainmail shirts you used to sell on etsy, and someone sends you bitcoins for one of them, and now instead of hoarding those bitcoins or cashing them out for USD, you spend them on something else in-game, because now YOU'RE the person in the middle of a market with a pouch full of coins in your pocket. And so on.
