Some people are fed up and/or too stupid to play by the rules whatever they are.
Everyone is fed up, that's no excuse for no obeying the rules.
I think a major mistake was made in the UK at the beginning with the 500,000 possible deaths or whatever it was that was modelled. This inflated scare tactic - or at least that is how it will be perceived by those who distrust 'experts' - just doesn't ring true, another version of project fear. When it turned out to be inaccurate, notwithstanding as demonstrated by the same expert community, then all other warnings can be treated with a pinch of salt as well.
It doesn't help there have been too many high profile cases of the 'elite', those who set the rules, exempting themselves from obeying them. That's been an unmitigated disaster.
