"if you live without money" – do you mean living on land while others pay the taxes for the your control of the ground for you?
(there is no unclaimed ground, so wherever I live I exclude others from using it)
But the police isn’t among the main reasons why I need money. The least avoidable reasons are medicine (no, you can’t produce that) and the dentist.
Those rely on complex production and delivery chains that would be hard to realize without money.
