This is one hell of a hottake. Property can be rebuilt. 9/11 was traumatic because it presented a level of vulnerability the American public hadn't felt before. Before 9/11 the proverbial bad guys were always "over there" and abstract in the minds of the U.S. people. 9/11 exploited vulnerabilities in domestic infrastructure to attack domestically, causing the eyes of the public to swivel from foreign battlefields to paranoia about its own soil and security, a massive change from the way such things had been addressed previously.
Covid is the same thing. These aren't "America" problems. Deadly diseases wiping out huge swaths of a population was, to the public, something that happened in poverty. It was a "China" issue, or an "Africa" issue. We were dissociated to the point that people have been pointing out or vulnerability to mass pandemics for years and there was no major update to our system of response.
