No; the argument is much closer to "if you don't make cryptocurrency basically the same as fiat, by building the same systems on top of it, it's useless to the vast majority of people."
That is just an observation, not an argument against building, improving, and using crypto.
Cryptocurrency doesn't need to do everything for everyone at all times to be a useful thing to have in the world. It only needs to be helpful to a subset of people, in a subset of situations, some of the time.
I'm happy paying by card for ~100% of my daily transactions, but I want cryptocurrency to exist should the need arise. The rise of authoritarian governments and policies across the world should've made that obvious by now. What's legal and perfectly moral today can become a crime tomorrow.
