You're assuming that you will only be able to purchase physical, ship-able things. I'm sure you'll also be able to buy virtual gift cards, WoW subscriptions, cell phone plans, game purchases, iTunes, stocks, etc. With the current (you must give the companies your CC number), only the companies you have done business with can take your money. With the twitter thing, ANY business that does transactions over twitter could potentially take your money (or people use your money to get stuff from them).
