Monaco gets away with it by being really, really small and really, really, really rich
So can survive buying utilities from elsewhere if you don't need much of them. So, you could probably, I dunno, make a small part of westminster independent and have it work, but you'd have to deport anyone with a personal fortune less than about 3 or 4 million.

Monaco has little tax but then has no government support or facilites, you pay directly and extortionately for absolutely everything from school to rubbish collection as far as I'm aware.
