I found this little experiment helped me shake off worries of "so many evil people". I started asking everyone I came in contact with, "What would you do if the government was gone overnight?". There wasn't a single person who said I would go on a killing and looting spree lol. Most people gave a positive response like " yeah no more taxes"..... You do run into the usual issues, muh pension and muh roads, but at least they were positive about the concept.

Try it out where you live. It would be interesting to see the results. I do live in The Democratic Peoples Republic of Canada-stan, I don't know if that would have any bearing on different results or not.
