There are porn addicts, and there are men with delusional thinking about women because of porn.
There are sports addicts, and there are people with delusional thinking about life because of sports.
There are gaming addicts, and there are people with delusional thinking about life because of gaming.
Should we ban or severely restrict alcohol, sports and games?
If porn were to have the same restrictions, we would have mandatory ID checks, in some states, the state government or contracted organizations would be the sole distributor of porn, and some counties would ban the retail of porn completely.
There's simply better comparisons than to alcohol.
1. States with ABC stores.
2. In every state except Washington
There are mountains and mountains of evidence documenting the harms that drinking at young ages (and in general) introduces.
"Evidence" suggesting that porn gives men "delusional thinking" about women is dubious at best. Evidence documenting that men's delusions about women are primarily fomented by viewing porn under 18 is even more scant.
