Those properties conferring value is contingent on a positive valuation for the underlying good in the first place.
If I had a bank vault that could only secure normal water, would anyone be impressed that I could secure it really, really well?

If Bitcoin could perform those functions so well for actual money, that would indeed be remarkable. But I will not agree that the 'nothing' the ledger tracks is money merely because it would be wonderful if it were.
