I agree with the principal of that commentary but in practice the "limited supply" aspect is not quite true because Bitcoin will be levered. Any limited supply asset base is always levered in order to meet liquidity requirements in its derivative markets. If the banks don't do it, the free market will in order to achieve price stability in certain trading sectors.

Despite that, the fact that Bitcoin is an electronic "bearer" token means it is more accessible to the ordinary holder so its easier for people who actually want to hold the base asset to do so.
