Good article.

Two things were not addressed though, which I think have a bigger impact than the things he mentions:

1 - scalability (e.g. transactions per second) of the bitcoin block chain is abysmally low. So low in fact, that today’s society would crumble on it as it currently exists;

2 - credit markets are not addressed. How do you loan money in a bitcoin world? Our society is built upon credit transactions, from buying houses to wasting money on gadgets with credit cards. If debt cannot be issued, then it will never amount to more than second place. Perhaps a medium of exchange for the Zimbabwe’s of the world, but not supplanting a modernized country’s currency.
