Yeah I agree that lockdown has basically disintegrated, but i think part of that it that it was so weak to begin with and that the rules are so nonsensical now that people don't really see the point. A number of people (including some of my neighbours) were always going to flout the rules out of sheer stupidity/selfishness, but I think a fair few are forming their own conclusions about what is reasonable in the absence of any clarity or logical consistency from the government - obviously as non-experts with their own self-interest in the mix they are not qualified to do that. Ultimately, anticipating the public's habit of misinterpreting messaging, whether through inability to understand or through conscious exploitation of ambiguous wording, is the government's job. I've been involved in writing guidance (albeit not public health guidance) and most of the work is ensuring there aren't any loopholes and that what you've written can only be interpreted in the way it's intended.
