There are any number of alternatives, I favor a walled off whitelisted subset of the internet that requires age verification and then we can let kids on that and otherwise ban them from the general internet and also ban internet enabled devices in general. However, this costs and undoubtably wouldn't be perfect as there are people out there who want to chat up your kids, look at how much work a roblox style site needs to do against internet users who probably shouldn't be chatting up kids.

For those precocious kids who parents decide should be the exception because they are "good with computers" well I'm thinking some sort of waiver would be required that held the parents responsible then maybe let the kid hack on the internet but this is an unpopular view, the unpopular part being the "parents being responsible for their kids" bit.

But in general I think its a tough time to be legislating this stuff because "reasonable perspectives" are not what we are voting into office right now lol
