I'm sure banks and credit card companies will use the entirety of their resources, both political and capital, to ensure that no organization is ever permitted to enable money to move this easily. But, really, it should be one of the primary things that the public should be fighting for. And it will be a fight, quite possibly a literal one. We're talking about nothing less than cutting the financial throats of every banker in the world. When it comes right down to it, though, it flat out does not cost more to work with large numbers than it does to work with small numbers. The idea of the bankers or card processors getting a percentage of every transaction is fundamentally flawed and unjustifiable. Of course, this is operating on the idea that a market should be based upon people trading value for value... an idea that doesn't seem to have much footing today. If you have no value to offer, but you've got the political capital to get people forced into the playground you own, that's seen as successful business as well.
