Alternate explanation: you work from home (thus aren't forced out of the house) and you are entertained enough by HN and Reddit and Netflix and whatever you do to have no real desire to leave, and since you have any concern about the virus, you confuse your indoor shut-in lifestyle (which most of us have) as some positive premeditated rational character trait that everyone else lacks.
I'd wager that explains almost all of the self-congratulating I see online.
