I agree that it’s a question that needs to be asked. I am definitely not a doom monger but we do need to start planning for a future that includes these kind of scenarios. Otherwise it’s all knee jerk. So say we have to have social distancing measures for the next two winters which isn’t beyond the realms of possibility. What are we going to do in that situation?
Personally, I think "some" level of social distancing will be with us for many years, whether an actual strict requirement, or whether simply out of habit/personal choice
Obviously, if infections/deaths start to rise, then we'd need some kind of legal requirements (social distancing, essential workers only, lockdowns, or whatever), maybe through a return of the tier system, just to keep it all under control and stop the exponential spread.
But even if not legally required, there may well be a preference for people (who consider themselves at higher risk) to make their own judgement re social distancing to give themselves confidence, i.e. avoiding crowded places, avoiding large gatherings, avoiding cramped settings such as theatres, sports stadia, etc. That's "their" choice, but it may prompt changes in the venues, i.e. some may voluntarily choose to limit admission numbers in the hope of attracting "worried" customers by making them feel safer.
Not disimilar to Saga's announcement yesterday that they're reducing the number of passengers on their cruises, i.e. to give the passengers more comfort and space on board, i.e. less busy buffet breakfasts, less cramped bars and theatres - that kind of thing will help persuade customers that they're taking covid seriously and taking precautions to help avoid spread of infections.
