The principles of reducing social contacts, and avoiding crowded indoor spaces are sound.
But we have to avoid destroying the economy, and mental health.
Lockdown deprives us of our humanity. I do not laude totalitarian China where people self censor any thought that is remotely anti-government. Many of those pesky mask-exempt people have additional needs that would have had them dumped in an institution exist, forgotten about, not actively live within society.
Many of our rules are contradictory. Last week I could go and sit 2 feet away from elderly DM in a busy cafe, but I wasn't supposed to sit 2m+ away in her lounge.
I can go for a drink with 5 other friends in the pub. But the substantially lower risk activity of taking two families of 4 for a walk is illegal.
I abide by the principles of seeing less people, keeping my space and trying to do what I can outside, but I'm not going to slavishly follow rules that do more harm than good.
Ultimately we have to live with this virus, as we live with other contagious killers like flu despite the vaccine of variable efficacy.
