Yeah his point suggests we should stop ID'ing at liquor stores, physical porn stores, etc.

I'm not suggesting that actually. I look at my nephews and see them buy cigerettes, vapes, etc from small dealers instead of stores. Not saying we should just let them smoke, just expecting that they will be able to circumvent online age restrictions as well.

My question is: are digital age verifications the best way to protect kids from harmfull effects of pornography? And my worry is: what unwanted side-effects will age verification have for our society as a whole.
