Can someone explain the 'it's about track and trace' please. If I have 10 people to my house and then find I or one of them has been explosed to covid it is very easy for me to contact the others and let them know. If I go to the pub or restaurant (which could be anywhere) where some people can refuse to give details or give false detais if they want, it is much much more difficult to contact everyone. I know many people don't answer the phone if it isn't a number they recognise. I just don't understand that argument at all.
What makes you think people who have been breaking the rules already or are unsure of the rules or just dislike authority are more likely to tell the truth in a private setting?
If you are in a covid safe setting then you are less likely to contact the virus in the first place. It doesn't eliminate the risk but it makes it less likely.
If you are in a private setting the 'fuck it' principle applies. Friends and family go 'fuck it' and give you a hug or kiss or forget the rules after a drink because you aren't in a formal setting where theres 2m rules / social pressure to follow the covid rules. The idea that you 'trust' your relatives and they 'couldn't possibly' have been exposed is much more likely. We KNOW most transmission is occuring in this way.
This type of interaction is also not a priority. If the track and trace service is overloaded we need to prioritise the situations people come into contact with others.
We want to minimise outside transmisson from non-formal settings (such as large family parties) to protect and stabilise the number of children being pulled out of school (which will include large numbers who have been following rules and perhaps are more vulnerable). There is a certain tension where parents know other parents are being knobheads and this puts them at risk.
In a formal setting yes you could give false details but most people can't be arsed to. They are simply too lazy.
In a private settings with a lot of people present you might not remember who you've bumped into or who you've had around your house if you've had numerous social gathering of a larger size in close proximately but you are more likely to remember going out for an occasion / friday night etc. There is no record keeping at all.
If you are going out for a meal or a pub you tend to stay local to where you live much more. If you visit friends and family there is a higher chance of moving across the country to do so - what the government don't want is too many new clusters popping up in places far away from the current hot spots. They would prefer to concerntrate resources into areas with high prevalence rather than firefighting across the country all at the same time.
There are lots more reasons too.
Its all about trying to prioritise, formalise and minimise work for track and trace.
Its not a straighforward answer but I hope that does make some sense.
