Unfortunately no rules will work as so many people are not following them.
They are even less likely to follow harsher rules.
Some people just can't afford to follow rules and lose income.
Many people can't effectively self isolate because of their living situation.
The government messaging is poor, conflicting, confusing and at times hypocritical and tone deaf, and they have lost many people's confidence.
Some people cannot understand that a virus will replicate regardless as long as it can find suitable hosts, in a relentless mathematical way regardless of political views or how hard things are.
I think the only thing which will work unfortunately is people seeing with their own eyes people around them getting sick.
As so far only about 8% of us have had covid, it's not enough for the majority to really understand from their own experience.
There's no good solution, but slagging each other off is not going to improve things.
People behave differently when in difficult situations, and that's what we're up against.
I have no answers, just my thoughts
