Sure. But isn't that a quintessential example of "easier said than done"? Like it's not a solution on it's own.

IMO metaphorically we have lions waiting on the edge of camp to prey on the weakest of us. Sure we can teach kids about the lions and keep them away from them whenever possible. But it would also be prudent to remove the lion's easy access to vulnerable people.

I think age restricting social media is akin to putting a fence. Not gonna stop determined lions or children, but it will eliminate the lions' line of sight.

I don't think age verification for accounts fundamentally requires giving every corporation our ID. We legislate it such that corps are only required to cease services upon suspicion(reports etc) and have an appeals process that legally cannot use direct ID verification. Instead they use 3rd party verification like online banks. This is already a working alternative method used to access Canadian government services. It piggy backs of the security people already have on their personal finances. The 3rd Party simply verifies the person is of age and discloses no other data. There may need to be some tweaks to that model but it's already working in Canada.
