One thing that would be nice is an automated take down. Anyone who no longer consents to their porn being hosted (or who never consented) can have the selected files added to a database and all porn sites would have to take down based upon matches to this database. This technology already exists with PhotoDNA for fighting known child porn (though I think the technical details are kept secret to avoid people finding work arounds).
As long as one draws a line between consensual and nonconsensual porn then I think you'll be able to crack down on the non-consensual material without having to worry about the failures of a 'war on x'.
Think of it like the difference between cracking down on weed and cracking down on synthetic 'weed' that is killing people. Or just look at stores that are able to sell alcohol. Because it is generally allowed, specific bans are much easier to enforce because business likes keeping the legal status.
This is why I use smoking: it's also legal or semi-legal, it used to be prevalent but its popularity cratered.
Not sure if he's right, but it's certainly a reasonable theory.
He also did a TED talk briefly touching on the subject.

Also being famous does not automatically make you an expert.
Edit: googled citation for criticism of the SPE https://pubmed.ncbi.nlm.nih.gov/31380664/
Same with porn and Pornhub. But it is the mental tobacco of our time.
You may want to check how early does porn (or sexualised images) exist. "our time" may turn out to be "since we discovered drawing".
Hemp smoking, on the other hand, has been traced back to many prehistoric sites in asia and africa which would fit your description much better.
We had obese people since at least the first settled societies. But it was nothing like today, both in how widespread and how extreme is has become.
Same with drugs. An opioid epidemic pushed by mega pharma is nothing like a shaman serving ayahuasca.
A nude cave painting or a figurine is nothing like thousands of hours of streaming porn. Barely related.
Whether it is bad for willing actors also needs citations. I don't know why people do it. I can think of some cases where it seems to have solved a psychological need, and they went on to lead successful lives afterwards (like Sasha Grey, or Sibel Kekilli).
Edit: googled article about Sasha Grey, with her quote about women in porn: "the reality is that there are a huge amount of women who are very happy with their careers and where they have gone in their lives"

I’m very curious because I think the existence and availability of porn and the sex industry is very important for the well-being of lots of people. Definitely some problems.. but I’d parallel those to problems with prohibition and suppression.
Have you always held this opinion? Are you religious?
As I get older I'm expecting more and more to have a future generation look at our with quite a dark opinion.
