The current fiat system consists of different systems that are interdependent through the defects of the current main stream economists, and the fact that central banks cooperate.
It's a flaw that central banks cooperate?
A new thing is the loss of anonymity, the anonymity is a requirement for free individuals who comprise the free market system.
For all intents and purposes, once the mainstream adopts bitcoin, anonymity will be next to nonexistent. Not because there'll be any changes made to Bitcoin. But bitcoins pseudoanonomyity only works for people now who understand what it is and isn't and take active steps to remain anonymous. For the mainstream, the record keeping of the blockchain will yield the same, if not more, information as is collected by banks and credit card issuers. Except, instead of it being only in the hands of those companies, everyones transactions will be out in the open for EVERYONE to examine.
I don't see Bitcoin as being the winner in that case. Yes, right now, small group of knowledgable users, yes, it wins, but only for people who proactively take steps to preserve it.
