In my opinion roads, police, fire services couldn't be built/services be offered without government involvement!
Opinion based on ignorance.
There are already such things without government involvement. Hell, my fire department is private.
MOST fire departments in the U.S. are private. This again illustrates the large gap between perception and reality for many people when it comes to what they want/think/expect of government, and what actually occurs.
(Also, yes, there are plenty of private roads and gated communities with their own security forces in the U.S. Guess that should be pointed out too.)
Again, people are ok with using force against humans as long as there is some benefit. Like with slavery.
That's really the bottom line. As long as I claim positive benefits for someone/everyone, and don't mistreat you too badly (or at least sweep the messes under the rug and just wave them off with "well, most people pay taxes, they should have too,") then I have some moral right to steal from you.

Double standards. Double standards everywhere!
