@steemswede 's post is a great resource on the subject (up'd!), but I see your point as well @steembriefing - anyone who oversimplifies the benefits as obvious, based purely on the absence of government in the equation, is motivated too much by ideology.

Government waste reduction? Check!
Increased and More Responsive Security for Citizens? Most likely!
Better Results in Criminal Investigations Leading to Justified Prosecution and Just Punishment? Mmmmm...
Overall Harm Reduction Leading to a Healthier More Peaceful Society Overall? God knows! :-)
