The hand washing was emphasized early because of some studies that purported to detect live virus on surfaces for a long time. That was later clarified to mean some RNA fragments persisted, not live virus. I have not seen a quality study on viral persistence on surfaces in contagious form. RNA alone isn't going to give you the illness.
I still wash my hands when returning from outside anywhere, it's good practice for general reasons. I THINK the transmission is mostly aerosolized droplets of moisture that someone encounters. Obviously, if those droplets fall on a surface indoors, they will be contagious for some period of time, probably hours, I don't think days.
This could be wrong, so don't make book on it. Just wear a mask. We could lick this thing if everyone distanced and/or wore a mask.
I don't personally view that as either hard to do or some kind of weird government plot to take our guns and lock up Jews, or whatever the latest Facebook thing is.
