My strategy exactly. Perhaps not as extreme ..but similar. We assume everything is unclean . Plastic bags should be OK after a few hours. Coats etc left all day in a warm car are sterilised. I use different pullovers every day and only wear the same one three days later.‘That’s my working principle. I assume that inside my home is virus free and that everything outside it, including people, will infect us. The front door opens into a “boot room“ beyond which is the hallway. Nothing, including groceries, post and parcels makes it out of the boot room and into the house without being cleaned with an anti-viral agent. Apart from me and my wife, no one is entering the house either.
There is a good network of isolated paths in the countryside near me too. I can sometimes walk, run or cycle for a couple of hours and see nobody. This weekend has been very different, it’s been very busy, lots of families walking and cycling. Surely shutting the boozers hasn’t made that much difference? Hard to believe all these extra people are normally downing ale.
No I think your additional walkers are the people going stir crazy at home.
