Volatility will go away eventually, yes. But not quickly. And that's why stablecoins are in demand.

its the other way around. the use of dollars is causing the volatility
Perhaps. But full on Bitcoin adoption right now is a theoretical scenario.
We have fiat now. Accounting is done in fiat now. The transition will take time. Making people get used to the concept of a deflationary currency will take time.
I can only think of an instant adoption with a huge catastrophe causing/accompanying it. And I don't think we wanna experience that + I don't think Bitcoin would be most people's choice just yet.
One of the beauties of Bitcoin is that it allows for a peaceful transition. First ultrasound reserve asset, then more and more medium of exchange and unit of account. Then stablecoins will become obsolete.
