As far as I can tell, you're operating from a presumption that you should be able to coom anonymously, or otherwise that it'd be bad if you couldn't.
I don't hold either presumption, but that's not because I necessarily think you shouldn't (well, you shouldn't be cooming at all, but that's not really my point right now). Rather, I recognize anonymous cooming as a quirk of the development of internet porn and its particularly (and probably intentionally) poor restriction from children-- something that's incongruous with how we deal with the distribution of "adult" material in literally any other facet of society.
You have to flash your ID and prove you're of sufficient age to buy guns, cigarettes, liquor, and even physical pornographic media-- which is also censoriously shrink wrapped. You have to flash your ID and prove you're of sufficient age to enter strip clubs. If you wanted to buy porn on PPV, you'd have to flash step to avoid your dad's belt because you were buying that on his account.
There's zero reason for this to not carry to pornography that happens to be on the internet, except for a barrier that's ultimately trivial for people that are of age. People already pay for pornography-- people already down money on OnlyFans. Being able to use a credit card at all is de facto age verification.
"Kids will always fuck and/or fap", now that I'm actually processing it, is a massively disingenuous non sequitur, grasping at straws. The entire point of the proposal is to mitigate child exposure to pornography, whether or not the success is total. (Nearly) everyone can agree this is a problem when public schools are stocking their library shelves with Gender Queer but somehow it's different when it comes to dealing with businesses that are invariably incentivized in the short and long term to expose children to porn. Businesses that have no reason outside of the borderline mythical goodness of their heart to do so much as preempt access with a trivial "I am over 18" button that is itself a trivially removable HTML element.
Kids watching porn are probably not having sex, and if they were, they probably wouldn't be wasting their time watching porn. We can't do anything about kids coming across the stray Hustler mag by the river, but that by itself is several magnitudes away from having over 1000 hours of sissy hypno at your finger tips by age nine after a fateful summer day where you made a lethal typo in your Google search query.
