Alasdair Macleod, who has a background as a stockbroker, banker and economist, has given a speech to the Committee for Monetary Research and Education: http://www.financeandeconomics.org/Articles%20archive/2011.10.20%20CMRE%20Speech.htm

Main points:
1.      Firstly, it is a basic human right to choose to save, without our savings being debased by the tax of monetary inflation. Those that are worst affected by this inflation tax are not the rich, they benefit; but the poor and the barely well-off, which is why monetary inflation undermines society and why the right to sound money should be respected. If government gives itself a monopoly over money, it has a duty to protect the property rights vested in it.
2.      Secondly, it is a basic right for us to own our own money rather than have it owned by the banks. For them to take our money and expand credit on the back of it debases it. It is an abuse of an individual's property rights and a banking licence is a government licence to do so. If anyone else was to do this, they would be guilty of fraud. Banks should be custodians of our money, and it should not appear in their balance sheets as their property.

In he's speech A. Macleod never mentions bitcoins. Maybe he has not heard of them yet? Somebody should give him a hint?!
