Having read a number of posts on this forum over the past months, suggesting civil unrest and so on, complaints about various things being "unacceptable", I get the opposite impression that there is a significant minority here who fit in that category, sadly.
The measures don't require 100% compliance, but do require it from the vast majority. The virus is highly virulent, so super spreader events emanating from irresponsible people do matter. Too many of these and we're fighting a lost cause.
And this is the reality of the position of the defiant, who say we should just let rip and take the death toll. Through their actions, and the consequences of those, logically they will push the government to a position of either giving in, knowing that thousands of people will suffer and die, or enforcing even harder.
If they were to have to give in, despite their desperate want to avoid the needless death and suffering, they (the government staff) will have been despicably placed in that position by those who will shoulder no responsibility for what unfolds (for avoidance of doubt, that's those taking choices and options away from the rest of us, by refusing to cooperate). Should that come to pass, thought will need to be put into how to make sure those actually culpable bear the burden of responsibility.
