The problem seems to me that users and miners have different priorities, and it's the miners who decide what the consensus is, not people who actually hold bitcoin. Of course, miners hold BTC too, and presumably want BTC to hold its value, so they wouldn't, say, intentionally inflate BTC (unlike a government-backed currency). But there's still a disconnect there. Consensus is consensus of miners, not consensus of users.

This is true in the abstract. However in the real world Bitcoin is in such a bind right now. While the USD had been stable in that sense since it came into existence.
