The main way banks make money is not via "fees", it's through their *monopoly on the creation of money*. When you sign a loan, they create the money from nothing, and then *charge you interest on it*.

One of the reasons the British were hopping mad at their American colonies was that the colonies started to use their own currency. This meant no need for loans (in British pounds), hence no interest! Moreover, no transaction fees either...not using British Banks or pounds as an intermediary for exchange of goods.

Bitcoin is therefore like sunlight to money sucking vampire banks...it sidesteps them and their whole model completely. If bitcoin takes off, I predict governments (read banks) are gonna start pulling all sort of BS out of their **sses to regulate the hell out of it.
