It does undermine it as a useful currency though. Can't set prices in bitcoin, can't safely hold money in bitcoin, can't safely sign future contracts in bitcoin.

I'm not sure how much of that was going on in the first place, but isn't it the goal?

It's volatile, just like any similarly-tiny market. You can't set prices in moon rocks, because a single round-trip to the moon would destabilize the entire economy.

But you could if trips to the moon were a daily occurrence, and the flow of moon rocks were relatively steady. Or compare buying stock from startups vs the Fortune 500. Bitcoin is too small to be reliable now, but the bigger it gets, the more resilient against such booms and busts it becomes. It's pretty well established that it's not a stable market right now, but that's obvious and it doesn't mean it won't become so.
