I agree. There seems to be a belief if we don't impose restrictions life for most people will go on as normal. It won't. We are already seeing lots of train cancellations due to staff testing positive or isolating, many health centres/hospitals are short of staff, my local chippy is closed due to staff having tested positive. My Christmas lunch has been cancelled because the host has tested positive today. Most people agree the number of people testing positive will continue to increase so the number of these sorts of incidents will also increase.
Isolating due to testing positive *is itself* a restriction. How many of these people are actually ill?
Now I do agree that a lot of people being absent from work due to actually being ill - which is quite possible given how easy it appears Omicron spreads - would have some impact on the economy and society for a short while. But the effect is being compounded significantly - due to government restrictions.
