You're probably right about Bitcoin not being fixable as a currency, and I say probably because I almost never speak in absolute terms. There are alternative cryptocurrencies that stand a chance of working out; the idea is mainstream now.

To me, it's a parable about the danger of following a pseudo-philosopher with no academic credibility and whose relevant oeuvre is fictional literature and not reading what Adam "Greed Is Good" Smith actually wrote about free markets AKA unregulated capitalism, which was that an economical system of people acting in their self-interest ends up promoting a greater economical and moral good for everyone but only as long as there are significant safeguards against abuse, but that's just my opinion.
