quoting a UK service is a moot point. UK banks have for years offered fast payment services. moving funds from one bank account to another has never been a problem for hobby amounts (under £10k) between english banks..

what bitcoin solves is this:
international movements instantly
no chargebacks
no requirement of central storage providers (banks)
no risk of third parties taxing you without consent
no risk of bank insolvency /bailouts
store as much as you want without question
transfer  as much as you want without question
no need for account application forms, id or being declined an account

"give a homeless man a bank application form. and he will starve waiting... give the man a QR code and he can instantly earn a living"
