The problem is that USA is already full of unlicensed guns and very specific gun ownership culture. In countries with relatively easy access to guns and low number of similar (Czech Republic comes to mind), gun ownership and it's culture were build on diffrent foundation, so you can't just copy this solutions to USA.

In Czech Republic you need an exception to buy something like AR-15, however the exception is quite easy to get. Long weapons magazines are limited to 10 rounds.

But most importantly, in order to buy a gun you need to get a license. This means medical check, passing a theory test, passing a psychological test and passing a practical test at the shooting range. It's not trivial at all.

The culture is completely different to US. Everyone is keeping their weapons in a safe. No bedside tables, car glove boxes or other nonsense. I've never heard of a child taking their parents' gun.

Granted, but culture changes, and in fact even if you were to focus exclusively on the mental health angle, you would have to leverage changing culture to make an impact grand enough.

Qua guns, teenagers in other countries don't have easy access to concealable firearms. Dad doesn't have one, and you can't waltz into a store around the block to get one.

The Uvalde shooter purchased his weapon a few days prior. Most school shooters do. Anything making that harder helps.
