How are temperature checks useful? I thought I'd read that people are asymptomatic for up to 2 weeks, during which time they can spread it. If that is the case, temperature checks do absolutely nothing to stop the spread here...

I am seeing this logic a lot: “this preventive measure isn’t 100 percent perfect, therefore it’s completely useless.”

Even measures that are only partially effective can make a substantial difference, especially at a population level.

I get the feeling a lot of HN commenters would recommend against condoms because they're only 98% effective, and only if used correctly, therefore completely useless.

No, they would not recommend the day-after pill as one of the core measures. Taking the temperature means you find out something is wrong a week late.

Because in this case, the measure is 0 percent effective. People work together every day. This virus spreads super easily. Telling people to stay home once they show symptoms does absolutely nothing to stop communal spread. If it did we wouldn't have these social distancing rules, and the entire country wouldn't be shut down.
