Every aspect of the modern financial system exists for a reason. It evolved over time to deal with problems. Things like reversible transactions are a feature not a bug.
Bitcoin is where all the gold bugs went who lamented the end of the gold standard. Most of these people didn't understand that at no point in history was the US dollar 100% backed by gold (or silver, originally). Never.
What backs the US dollar isn't gold or oil or anythihng else we dig up out of the ground. It's long schlong of the US military.
I've also said that crypt currency exists only because the government hasn't shut it down. All it would take is a policy change from the US government to say banks who have access to the US financial system cannot trade in Bitcoin and it would be over. Yes you could still have wallets (at least until the government starts going after Bitcoin farms, which again it could do) but what would you do with those coins?
Bitcoin is not, never has been and never will be an escape from the perils (some real, many imagined) of fiat currencies.
