That's not actually a response to my point though. My point was that the limited quantity of BTC is really only 'limited' by perception. Sure, the amount on the BTC chain is limited, but copy the software, boot up a new chain and you have another 21 mil to play with.

The reason the one has value and the other doesn't is pretty much down to brand recognition/network effect.

Though as I also said - in a central bank situation where a single chain is mandated, that's less of a concern.
