That depends on where you live. Prior to a recent move to a high COL area, it would've lasted me a month, with $50-100 to spare (rent, utilities, and food if I went for rice and beans and the cheapest meat I could find).
Cut out the optional services (streaming services) and fuel (not driving as much, $100/month fuel cost gets reduced to maybe $20 for the isolation month), and it can work in many parts of the country.
It probably wouldn't last long in San Francisco, New York, Seattle, and other high COL areas. And to make it last, you'd need roommates, which creates a hazard with regard to trying to create/enforce social distancing. But not every city or region has crazy high rent. Some places are still sane.
