The same applies to "lockdowns don't work." That is obviously complete BS considering there are plenty of examples of lockdowns that did work (e.g. the Aug 2020 lockdown of Victoria, NZ lockdowns, Taiwan, South Korea). But lockdowns can fail easily with noncompliance and inability to effectively quarantine the infected.
It's like saying boats don't work after trying to build one out of grocery bags or untreated plywood. Yeah, crappy boats are going to have leaks. Lockdowns are hard; it's not something we really practice (and worse, there are malicious defectors who want lockdowns to fail). A lot of people, we have learned, are selfish and unwilling or unable to make any sacrifice, even in the face of severe collective consequences, and worse, will sabotage efforts either for political gain or just the sheer pleasure of watching everyone else fail (and die!). I really don't know how we can expect global society to continue given how craven some people are.
