You’re confusing different things. “Contact tracing” has nothing to do with touching things. It just means you had some kind of contact with someone who had covid. Not even physical touch, just being relatively close.
Covid does not spread well through surfaces. This created huge waste as people were trying to deep clean with isopropyl alcohol, resulting in isopropyl alcohol shortages and companies putting in more dangerous forms of alcohol in hand sanitizer. It was completely unnecessary.
Which isn’t what the covid contract tracing apps did. They just looked for proximity. Which makes sense, because covid is primarily transmitted by breathing around people.
Covid doesn’t transmit on surfaces very well.
Other things do.
Then we didn’t learn it from covid.

And since we’re talking about covid in a mass context outside of just medical professionals, that’s entirely justified.
