I'm not sure what you are arguing here.
As to humans not changing their habits easily, I'm sorry but I can't agree -- after all people fell into the habit of wearing car seat belts and not smoking in public places easily enough, once they had to, and have adopted the habit of buying and carrying smartphones with them with remarkable enthusiasm, and using them to communicate on social networks like Facebook and Twitter, and to using these as their main sources of news, without any degree of compulsion.
My point is that, when lockdowns begin to be eased, all businesses are going to need to rethink their business practices to comply with whatever regulations about social/physical distancing are in force at the time.
These regulations will have a bit impact on all business -- the layout of open-plan offices is going to need changing in many cases, as are these offices' washrooms, meetings rooms, break rooms and kitchen facilities.
The regulations will have a similar effect on retail businesses, including all forms of hospitality and catering, as, of course, will changed market conditions in the recession that will be upon us -- while people may well ignore the risks of congregating in bars and clubs, if they're out of work, then regardless of their views about the risks, they might run, they won't have the money to spend in such places.
