Please let's not compare something that isn't replaceable to something that is replaceable. When people start telling that Bitcoins success is guaranteed by the success of gold, then is the time when serious investors skip because of excessive cult behavior.
Bitcoin has many of the characteristics which give gold its reserve utility. In fact, bitcoin price movements have tended to correlate with gold more so than with other investments. Certainly bitcoin is much more secure against counterparty failure than are any non-physical claims on gold, and it is precisely security against counterparty failure that gives physical gold it's principal distinction.
Sneering at the facts does not change them. Nor does it make people who are worth convincing esteem the facts less highly.
