In the end it boils down to the question of whether you trust people in general. I do. And if you don't, you're afraid that they'll be mean to you without the presence of some punishing force...I would suggest traveling around a bit more.
It isn't a matter of trust. We have history to show us people are animals. While it has lately become vogue to sneer at the U.S., our laws, police and fire forces are the reason people KEEP coming here in droves. Unfounded trust provides a scammer's paradise because people are animals.
Edit: nevermind. I'm going to skip ahead a few pages. From time to time when they're focused on price I forget how annoying and dim Libertarians and Anarchists are. I need to jump ahead to some dinosaur charts or something. The naivete is exasperating.
