Here are a few questions you can ask yourself.

1. Do you think someone would be more or less likely to break into a house or attack someone if they assumed they were armed?

2. In general what provides better service and efficiency, private business or government services? Why would policing be any different?

3. Police are just a group of people. Why is this group uniquely able to provide security and another group would not? Why would we assume that police can offer this service better than every other possible group of people?

The concept of a world without government seems impossible at first but the more you think about it the more you realise that all the arguments for government quickly fade away.

The biggest criticism is that we would just end up where we are now with one monopoly in control but that hardly seems like an argument against anarchism as even in that worst case scenario we end up only exactly where we are now.

For" a New Liberty" is very in depth but if you want a succinct overview of Rothbard's view of the state then I would recommend reading the 60 page "Anatmy of the State" as a good starting place.
