'The best part is this,' Srinivasan said. 'The people who think this is weird, the people who sneer at the frontier, who hate technology, won't follow you there.'
But people who will be quite happy to exploit your deregulated society will be right there with you!
Complain all you want about 'big banks' unethical behavior (really, keep complaining, write to your local MP/senator/whathaveyou, make sure the issue doesn't get dropped) but government regulation of banking means that if you put your money in a bank, you can be sure (at least up to £85,000 per Bank in the UK) that you will always have access to that money. Without regulation, then you have situations like with Paypal where the holder of you money can just up and decide "Nope, you can't have it anymore. It's ours for at least the next 9 months. Oh, you want an explanation? Too bad!".
Or how about enforcing standards, like power supply? You want a situation where not only does every device have it's own plug, but your house may not even supply the same voltage or frequency as the neighbourhood a mile away? 'No government at all' works fantastically when all your actors are rational and honest. That is also true to Communism. Finding this mythical group of rational and honest actors (and keeping out even a single bad egg) is the hard part.
