It is a bit bizarre to read about police state where the police are a monopoly ran and controlled by the government and then call it capitalist.
- police writ large
- police monopolies
- any given police policy and its interaction with capital
Anyways, if police are supposed "to defend capital", then a policy of stealing capital from private individuals is exactly not capitalistic.
And people's personal property is not normally capital in the sense of capitalism, it not generally being the means of production or of reproducing capital itself. This is a really basic point which has me thinking we disagree on the fundamental terminology. Capitalism isn't a synonym for commerce, assets are not necessarily capital.
