It's complacency. People think about the here and now, not what the situation will be 7 days afterwards or more, when these measures will actually have visible effects and may ultimately impact whether they catch the disease and/or can get effective treatment for it.

I think to give these people a minimum benefit of the doubt, we as a species have never before dealt with a virus that can last on surfaces for days, incubate for several weeks, and remain in lungs for over a month beyond a “recovered” patient testing negative. Not to mention the known yet nearly impossible to measure asymptomatic spread.

All of this is new in so many ways all at once. Frankly I think it’s so beyond our expectations of what a virus can be that many people simply don’t believe the facts.
