The only thing it achieves is ever growing helicopter parenting and related anxieties ... while the same people who complained about parents not controlling everything complain when they try.

We expect shops and passerbys to not sell porn or steal from kids in real life.

Now imagine all government restrictions on these are removed, and there is a store within walking distance of your house that is staffed by employees that will willingly, without question, sell these items to your kids and their friends? Is it still all on the parents to prevent access?

What about if this store has advertisements specifically targeted toward children? Or has discounts on cigarettes/alcohol/... aimed at the lower age brackets? "First pack free if you're under 18".

Now put this "store" on the internet, accessible from your kid's cellular device.

There's a spectrum here.

I'll give you a hard reason of which you must not be aware: it actually takes two parents to have a child.

Think about why that's important. If one parent is too addicted to their own usage of Instagram, and models that for the kids, the kids will pull that towards them, no matter what the other parent does.

You cannot monitor children constantly, unless you are are, say, a billionaire tech executive who has willingly ignored all data to show that his products have damaged society and children in pursuit of personal profit.

There is only one person in the world that can afford to do what you suggest, and his initials are MZ.
