Furthermore, there is plenty of criticism that could be levied upon central banking, financing wars between nation states being chief among them. There's an enormous social cost to central banking.
Unless you are sending huge amounts of money, bitcoin is more expensive.

You realize there's no such thing as 'free' right? What's the saying? "If you don't know who is paying for a product you're using that's free, you're the product."
And the cost of this to the end-user is the risk that if everyone simultaneously tries to withdraw their money, the bank won't have it. That's happened once in U.S history. I think it's a safe enough bet.
