My answer is Yes considering the fact that there are lot of local exchange on site i.e localbitcoin and on exchange forum like this!
While bank's and other form of payment are dependant on bitcoins. Bitcoins is independent of them.
Is the First banking system in existence without the need of government policy or any financial medium
This is one of the main objective of bitcoins (total control,Freedom)

Now, why are most financial institution launching series of bit-related prepaid & debit? The answer is simple and straight forward. They want to introduce rules. Mark My Word!Inotherword's they want to break the
main objective of bitcoins. And most bit user's are unaware of this.
Bank's cannot function fully with a virtual currency whose objective is to remain anonymous. This is against the financial rules. And, no bank will be willing to break such rules.Below is a snapshot forwarded to me via email by a colleague who placed order for one of such prepaid card.

He was force to submit personal document & proof of resident address during this process.
The summary of it all, he had to cancel this order at the end because he was told such payment does not support bitcoins and other virtual-related currency.
