I don't see how the government forbidding you from leaving your house can ever be considered minor.I'm trying to think of any such regime that has come about as the programme of a government which has been led by someone whose whole career has been libertarian, and failing.
I see no desire among the politicians in government in this country to use the current restrictions except as a measure against Covid, and the "authoritarianism" of which many here complain as minor, low key, and intended for specific purposes; they have also typically been implemented both later and more half heartedly than advised. There are advisors whose expert opinions on Covid lead them to specific conclusions about what restrictions are required, and for how long.
If the UK were genuinely led by authoritarian politicians, we would be seeing a very different style of policing, with much more aggressive use of the courts, and legislation that is both more onerous and more prescriptive. And we certainly wouldn't be seeing what some on here have described as reducing compliance without significant ratcheting of enforcement.
Those opposed to the government's policies on Covid should actually look at what an authoritarian state is like, and the implications that has - including on our freedom to complain about "authoritarianism" on forums like this.
