if applied in practice, produce a police force entirely compatible with anarchism.
But only guaranteed if someone were to enforce your rule #1... which of course would be incompatible with anarchism.
Hence the flaw in many arguments for various non-centralized forms of government. If the rules aren't enforced, they're likely to forcibly change. If they're enforced by some central authority, the government is no longer what you said it was.
My favorite example was the young woman interviewed during Occupy Wall Street, who said we should all abandon money and civilization and go back to being an agrarian society. When it was pointed out to her that such a decision would cause a massive die-off of American citizens, her response was "well, people die."
Ok, let's look at that for a minute, sweetness. You and your colorful friends develop an agrarian society somewhere, and let's say you're actually successful, in that you can adequately and sustainably feed all of your members with a little left over.
Then, one day a bunch of hungry brutes with guns arrive, and suddenly you find that the survivors in your little community are working for the brute squad, and life isn't nearly as nice. What are you gonna do about it? "Mike check!"
