I don't think it's necessary to prevent minors from accessing pornography. 17 year old teenagers have a sex drive, it's time that society gets over it.

It's not plausible to do that. So teach them what it is and that it's stylized and unreal. Tell them that you don't want it on the family computer or the family wifi. Teach them to identify and despise misogyny. Teach them how to resist peer pressure. Teach them that society has weird ideas about what counts as real sex, or improved or advanced sex, when in reality it's just a thing adults do to express closeness and have fun.

And then they will regulate themselves.

The real question is why is that a goal in the first place? What is the harm prevented?

The way I see it avoiding awkward conversations seems to be the most consistent "real goal" judging by other actions.

Given that I've not heard a proposal that wouldn't have also helped my parents hide the existence of gay people until I went off to university (and they tried!) - I wouldn't.

I'm quite sure ulterior motives explain more than stated goals, here and elsewhere.

Porn is to real sex like every YouTube movie about home improvement would only feature chainsaws, flamethrowers and jackhammers: it looks great - no doubt - but it's useless if you're looking for practical information how to fix your leaking roof.

So perhaps there should be good non-prude material for under aged people that are interested in the subject. If kids have nothing useful to watch they'll watch porn instead, right?

For example: I found a very informative book about drugs at school written by two guys that tried about every type of drugs in existence and wrote what to expect from it and what it's benefits and risks were. The section heroin basically contained the word: "NO". I don't think kids in the US had access to this type of information given what happened in the last decade with heroin because of 'protecting the kids' laws in schools.

Once you're competent in the relevant domain you can usually skim through those chainsaw and flamethrower DIY videos, find the parts you need and implement them with little issue.

Nothing. If your kid actively seeks out porn then chances are that he is already mature enough for it. Thus the problem does not exist.

Edit: and the things you should watch out for is not porn, but have you kid joined some weird religious cult or a gang - that can cause a LOT more trouble than having an awkward conversation about sex.
