The US Dollar is a commodity with a semi-guaranteed demand, barring no radical changes in monetary policy. That's what gives it a relatively stable value.
The same cannot be said for cryptocurrencies. Demand for them is speculative, and fickle.

Commodity money still has worth from what it's made from (e.g. gold) even if it's no longer used as money.
I'm not sure what Ethereum is.
I, and the rest of the world have pretty good faith that this will happen in April 2019, and pretty good faith that it will also happen in April 2020. I have pretty good faith that if it will not happen in April 2021, I'm more likely to be scavenging for bottle caps, canned beans, and ammunition[1], then I am to be be using eth.

Hmmm... I wonder what would happen if everyone tried to pay their taxes with Ethereum?
The government would, quickly, and decisively increase punishments for non-compliance, print or borrow a wagon-full of money to make payroll, and send the police, and army in.
Asset transfer is a better case, but why not use quite literally any other cryptocurrency for that, instead?
