It was good practice for pandemic response. I think (blasphemy, which on its own is wild) the global reaction was too strong on an acute level, but was worth it as prepararion for a deadlier pandemic.
Or it was too little because it still spread easily?
I'm on the border of three countries and you'd always see symptom reports go up in a region, sewage analyses go up, hospitalizations go up, and finally shortly before mortality started to show an increase (several weeks' lag from the moment of infection) they'd decide "guys, here's the statistics, we have to lock down now". Yeah great, now that everyone caught it they have to pretend being on the ball. And people still literally rioted against lockdowns. Or the masking thing, the resistance against filtering your breath... at this "too strong" level in your opinion, I don't see that the outcome was significantly different from "yolo protect yourself as much as you like but don't expect anyone else to be mindful"
In another time it might have been good practice, but in reality I think, between the grifters pushing fear and those just too self-centered to go a few months without a haircut (yes oversimplifying and straw-manning), it actually precluded the chance that many people will ever cooperate with a pandemic response again.
It was a natural reaction though. People saw the Italian hospitals overflowing and thought "oh crap! We can't let that happen here!" At least where I am they tightened and/or relaxed restrictions on a county by county level based on how full hospital beds were getting.
