> Why does the UK seem to take 1984 as a guide book, rather than a cautionary tale?
Answering a rhetorical question here, but the UK is an unreconstructed colonial government left over from the Empire. In some ways it hasn't really adapted to the independence of Ireland, despite that being nearly 100 years ago. Instead it runs a system designed for control of "distant savages" from London on an absurdly reduced scale, like someone trying to use Kubernetes for their "hello world".
Three of the four home nations have colonial office structures. There's a reason there's no Secretary of State for England.
Even within England, places like Stoke-on-Trent and Great Yarmouth get treated as if they were in remote inaccessible jungle because you can't get there on an Oyster card.
Brexit is where we find out which of the bits of the British constitution are load-bearing.
