But ETH is still tied to the dollar and that's where it gets its value, is in the comparison to the dollar. I don't accept ETH for a used car I'm going to sell. I accept dollars, though.
Although USD might be your preferred, many would happily sell a vehicle for compensation in BTC, ETH, silver, gold, euros, etc.
"Oh shit, the internet went out. Hope the value of my ETH doesn't crash through the floor while the internet is down...."
For people that look at it like that, sure. That's not how everyone looks at it though. I personally look at it with the aim of acquiring as much ETH as possible because I can see that the future economy will be built on it and eventually things will be priced in ETH.
Just because the transitions are slow and you don't see it happening, doesn't mean that there's not a transition happening.
