So I'm broadly sympathetic to that point of view, but I think you also have to account for the changes in the world since you or I grew up. I didn't grow up in a world where dozens of PhDs were using massive targeted AI computations to figure out how to manipulate me. I didn't have online Skinner boxes backed by, again, a horde of PhDs or equivalents with every motivation to separate me from my money, time, and attention. You need to present your children with some challenges and help them overcome it, but you can't put them in a cage match with the entire modern advertising industry, or expect them to figure out YouTube and the rather exploitative practices and dodgy videos kids can dig up, all on their own at the age of 5 either. I didn't grow up in a world of social media, and all the pathologies that come with it, many of which are probably much worse for developing minds than when I finally had a chance to get into it. (And, in fact, I've never had a Facebook account, and my Twitter account was created just for a couple of stupid sites that used it for auth; it's unused by me. The adult me rejected those sites from the get-go.)
I did grow up with some smart people trying to manipulate me in between cartoon breaks. (Personally I tended not to watch the most exploitative "cartoons that are just ads for toys" sorts myself, but YMMV. It wasn't my own brilliance, though, just my personal taste.) But it was very amorphous and poorly targeted at me personally. There's no AI chewing over my video preferences and figuring out what I'm most vulnerable to. It made for much better practice in becoming a bit cynical about such things. I also grew up in a world of video games, but again, the feedback loop was too big and amorphous to manipulate me very effectively. It was still potentially addicting, no question, but much, much less so than a modern mobile gacha game or something.
I'm taking a staggered approach myself. I know they have to learn themselves. I'm literally budgeting for them to buy a few things of their own free will, and then be disappointed in the result. It's part of life, and like many things, better experienced young while it still doesn't really matter. But I'm also moderating the rate at which this stuff comes in to them, because I'm not even particularly convinced it was a fair fight in the 1980s when I grew up, and it's not even close today.
