Voluntary altruistic compliance with light-touch measures would be completely undone by these selfish and ignorant minorities.
It would be up to the person/organisation/business to implement and enforce their own rules. Then the "selfish and ignorant" wouldn't have the opportunity to "undo" the measures.
Like our village pie shop. Even when it was allowed to re-open, they didn't admit any customers into the shop. Orders were taken through the window. Same with our village chippie who installed a hatch in their door to pass through the orders. Both instigated a card only payment policy so they didn't need to handle cash. There was no legal requirement for them to do that, no local rules, nothing to do with restrictions/tiers. They did it themselves, made their own risk assessment, decisions, etc.
Long before lockdowns, our village Spar shop imposed it's own form of rationing as they could see what was about to happen. They limited customers to two of anything/everything. No exceptions. As a result, their stock lasted weeks longer than the supermarkets and their local customers continued to be able to buy stuff. As stocks ran down, they started keeping things in the storeroom and only selling the really short stuff to customers they recognised!
The only "downer" in our village was the stupid primary school headmaster who held a whole-school assembly on the day they had to close down - all pupils, all staff, and parents were encouraged too! What a way to help reduce infections by cramming a few hundred people in a tiny, cramped school hall with no ventilation. What an idiot! Yes - it did cause a wave of infections in the village!
My point is that there are plenty of ways that people can take their own measures that don't necessitate trashing the economy, the education and mental health of millions of people!
