Possible yes. Practical for the average parent? No. I’m a pretty sophisticated technology and mobile user. I’ve built out MDM and MAM solutions for significant deployments of smartphones - setting up limits on individual phones is complex, time consuming, and unreliable. The median user can probably implement a time limit on iOS, but I’d guess 40% of them don’t do it correctly the first time. A gun is easy to secure. You either don’t have one, lock it, or lock the ammo and gun separately. Physical controls prevent accidental discharge and are easily understood by reasonably intelligent people. The gun argument is a bad comparison because the rational people who use guns as a tool get drowned out in the noise of paranoids and people selling gun swag.
