The government will just crack down on it eventually and the transparency of the blockchain will be used against you.
We need a political solution, not a technical one. In my ideal society I would still have private banks and I would have a currency 100% backed by real goods. There just wouldn't be a government bailing out banks when they screw up, vomiting up regulations and stealing your money every year.
That said, some of my friends went all in on BTC and got insanely rich, started buying islands in the Caribbean and places in Switzerland. Hopefully some of the crypto money will start a government-less society experiment somewhere, somehow, at some point.
