The valid point is this, in an enclosed space (restaurant) there is a higher chance of catching (any) infection. So one enters the restaurant with a mask, yet once seated the masks are removed. Most restaurants have air conditioning which recycles the air. So the "precautions" are ineffective.

Then when this is compared to mass demonstrations such as the recent BLM, where no social distancing was followed, few people if any wore face masks, the authorities did nothing to enforce their own rules about public gatherings.

All the while, every public event since March until September is cancelled.

There is no consistency to the enforcement of the rules.

No, Italy did not continue as normal. As stated, they were the first EU country to go into full lock down. The dramatic rise in cases there was because the industrial North of Italy was exchanging many people with China on business / work grounds. The high death rate was because there was a large number of aged care homes there.

Why New Zealand was mentioned, as stated above, the lockdown and isolation has proven ineffective because there is a further outbreak.

Lockdowns aren't meant to last for long, but if the worse the situation is, the longer lockdown might be needed.

Define the duration of "aren't meant to last for long". Define longer lockdown.

The initial lockdown has already seen many people lose jobs and businesses close. Governments are already handing out rescue packages to keep things afloat. How long do you think this is possible to sustain before things really break down?

Even at the very start of the lockdown, Austria had to put out an emergency call for people to work on farms to plant and reap the first harvests of the year, because they are normally reliant upon itinerant workers from poorer EU countries to the East and South to do the work.

Food and products don't just magically appear on the shelves. It becomes a chain reaction that flows onto the rest of society and the nation as a whole.
