Re authoritarianism I worry more about the G7s spokesman for Russia. Also I went along to spectate the Brexit court case but parliamentary democracy won that one https://www.bbc.co.uk/news/uk-politics-38733090
Anti-authoritarianism only flourishes when a significant number of people is fed up with what they perceive as incompetent leadership - at that point, the manners of such leadership start to matter.
That and of course the predicted drop in tax receipts due to Brexit has basically caused a widespread freeze on IT spending across the government. So a Digital ID has zero chance of being implemented in the next decade or so.
The "stiff upper lip" culture of basically just sucking it up may have a part in it. This thing doesn't immediately affect me or mine, so why fight it?
