You can use Liberty Reserve and then an e-exchanger that send money to Western Union (or Paypal).

For example, here's a New Zealand based e-exchanger: https://www.alertexchanger.com/index.html

I'm sure as the e-exchangers realise there is money to be made, they'll start adding bitcoins. Or perhaps a bitcoin entrepreneur can create one. Basically as long as you can somehow get money to western union, you don't need banks at all. Western Union may be seeing it's first proper revival since it's glory days in the 19th century!
