That's true, I also think that bitcoin may be very well accepted as a money transfer system. If there would be good options to cash bitcoins in countries, and that might become a reality soon, hopefully.
Wouldn't that be a good side-business for almost *anyone at all* who was willing to carry a small float of BTCs? Put up a sign in your regular shop window: "We buy/sell/send Bitcoins" (or whatever is appropriate). A customer comes in and agrees with your rate, say 2.5 BTC = 410 bhugretz. A receiving address is given on the spot and sent by email or SMS to the sending person. Add a fee to ensure transaction priority. The transaction is sent and verified. Profit of 10 bhugretz. Many people would be willing to pay way over the market rate for the convenience, less as time goes by and there is more competition. But right now in places where there is a lot of money transfer going on? Where you can go down to the store on the corner and don't have to go to the Western Union store five miles away in the bad part of town?
Just as you used to see signs in many shops "We send faxes. $1 per page" (or whatever). It's not the store's main business, just a profitable sideline with a very low entry fee and low running costs for the business owner.
