The sticking point for me is informed consent. We don't consider children to be capable of giving informed consent, which is why they generally can't enter into contracts. It feels like advertising has become so omnipresent that we don't even consider that to be entering a contract, but it is. They're handing away their data or having their desires manipulated, and I don't think children can be reasonably asked to make a judgement on whether that's a good decision for them or not. I do see the point that you're making about turning 18. Fortunately, I think that's somewhat of a self-limiting problem. If kids turning 18 genuinely can't withstand the ads, they'll start filing for bankruptcy and credit card companies will stop issuing them lines of credit.
