This should only be attempted as an exercise in removing every law & department, one by one, replacing each govt entity with a private sector alternative or three, until there is no govt left.
If you just stopped offering all the services that the govt offers at once, there would be chaos. This is why most associate anarchy with chaos. That's how it's always been implemented before... But Argentina's Milei has proven that you can cut back quite a lot in a single year without societal upheaval.
So just do this, year after year, department after department, until they are all gone. Every last department, with criminal courts being the the last one.
That means you centrally plan nothing at all, let the free market optimize all markets, and have no policies to enforce, nor enforcers to command.
