The Governments/controlling entities would have to agree on essential/non-essential, and we'd all be dead by the time western countries agreed that Financial institutions aren't "essential", if at all. Those being in a fragile state wouldn't be able to cope.
Normally I would totally agree! Look at the EU negotiating with Canada! But they seem comfortable telling people not to go into parks etc.
Financial institutions that are fragile wouldn't survive under the current constraints. Many businesses won't survive. They might have a better chance under an induced economic coma.
That and how does one monitor/prevent non-essentials from just ignoring and scampering on as normal? Unless there's a hefty( and I mean obese ) penalty when the world comes back online?
No different from the social pressure to keep out of parks and to wear masks. In my opinion much of the mask wearing is a signal to others to obey all the other rules in place. That's part of why I do it. And obvs also so I can stick my tongue out at people I don't like.
