Most people clearly aren't very good at driving either, and any of them at any moment could swerve and kill you as you walk down the sidewalk, but surely that doesn't stop you from going outside.

Of course I expect people to trust me, it is consistent with how I function IRL.  I understand I'm a stranger to you and the majority of the world, but I can't help that.  If there was a way I could make the coins in a cost-effective manner that required trusting nobody, I'd do it.  Doing it and giving out my real world identity and allowing people to have recourse against me is second best.  Nobody is complaining and saying there shouldn't be a physical bitcoin.  Just don't buy one if you think I might rip you off for your 1 BTC!
