Though I generally agree with the sentiment, there is one significant use case -- transferring money across country borders. Currently, transaction fees on cash transactions are much much higher than they are on cryptocurrencies (maybe except bitcoin) and so this would mean that, in theory, they could be used as a way to transfer goods across country borders.
This has always struck me as…I don't think a "weak" use-case is the terminology I'm looking for, but maybe "fragile"? What I'm trying to get at is that I'm not sure that the existing non-crypto money transfer services have to charge as much as they do to be profitable. If cryptocurrency-based transfers get popular enough that they're perceived as a threat, then I suspect Western Union and friends -- or perhaps new entrants to the market -- will introduce "new products" that are more competitively priced.

If you think malware ransom payments are the primary use case for transferring money across borders then you should get out of your bubble and make friends with people originating from other countries or with family back in those countries.
