Then there's reality.
Consider this recent offering from Fred Reed concerning why it is so hard for empires to defeat one particular region:
"In Afghanistan there are no targets of high value to destroy, no clear lines of supply to be cut, no cities whose capture means you win, and no concentrations of enemy to be easily killed."
And this is in a region where there is little liberty. Add real liberty to that equation and the odds are stacked even more in favor of the home team. Without a city to capture and win, you have to defeat each and every individual. It won't happen.
The State endangers me and it endangers you. Stop pretending otherwise.
