Does the price volatility argument for Bitcoin never succeeding as a normal currency make any sense?

I've heard many people including economics specialists say that Bitcoin can never work as a valid currency because of its price volatility, but isn't this missing the point? I mean isn't the grand idea that Bitcoin would eventually become the dominant world currency, and if this happens people will be no longer swapping bitcoin for dollars or euros etc because they would be either largely worthless or non-existent. Therefore this price volatility would no longer exist, as Bitcoin will just be traded directly for goods rather than other currencies. In the hypothetical situation that Bitcoin does reach these heights, the volatility issue would surely be seen as just an artifact of an early adoption phase of Bitcoin. Or is there some other way that I've overlooked/don't understand that you could see price volatility persisting in this scenario?
