I assume due to your personal circumstances that you've not been out and about to supermarkets and the like during the last couple of months but surely you're aware that there's still a significant number of people that completely ignore social distancing guidelines? That's before you even consider whether social distancing really is possible in many work places. I've been to local takeaways that have 2 or 3 people working in small cramped spaces where they cannot work while socially distancing. For all the good will in the world, I very much doubt social distancing will be successfully enforced when more businesses open, it certainly hasn't in a lot of businesses that remain open.
Unlike 99% of other workers, footballers are going to be tested 24 hours before they return to training and play matches, isolate for 24 hours before being cleared to train/play. The chances of an infected player or staff member making it onto the training ground or pitch is will be considerably lower than an infected office, factory or shop worker. If this is enough to cancel out the increased risk of spreading the infection through contact sport then football would be safer than other industries. That's the main question that needs answering and I'm sure the PL will be taking private and government advice on this.
Any player that doesn't want to return, if and when it's decided that it is safe, shouldn't be forced to and they are fortunate enough that the majority of them are in a financial position where they can go unpaid if they choose to do so. Joe Public will very much likely not be in that position.
That has been mentioned but it would be counter productive if teams were still playing in the same City.
