I think where we live is a result of a combination of life choices and circumstances, and life isn't necessarily fair. But if we have chosen to live somewhere where you might have to wait an hour for an ambulance, you need to drive or cycle if you want to go out to the cinema or for a meal and you can forget any chance of ordering a takeaway delivery.....the upside might be that it's much more proportionate and reasonable to go for a longer run. That's not to suggest we should ignore the guidance when it suits us or look for little loopholes to suit our personal preferences, just to suggest that the situation is different in different locations. And if someone in a crowded city can't go out as much or for as long as they would wish that's a real shame but not a reason for others in different circumstances not to.
