I agree with the criticism that you're making, but I think your police force comparison contains fallacies. Human institutions cannot be told from the assumption that we all began as isolated individuals and arrived at the solution of centralised control as the outcome of a set of rational collective choices.

I'm sure there are many 'origins of the police' narratives, but one I know is the Metropolitan Police of London were developed explicitly to curtail the dock workers from exercising their customary right to take small amounts of the goods they were unloading home with them. To generalize from this (a dangerous game, I know, but this seems to be the flavor of the thread), institutions are constructed to protect the interests of one class from another
