I agree with basically all of this. Although an interesting and I guess somewhat relevant thing about alcohol is that here on the continent (in Spain, France and Italy for example) it's more normal for kids to have alcohol at home when they're 14, 15 or so, and yet they have way less problems with underage binge drinking compared to the UK, where alcohol is strictly controlled and yet it's a huge problem. That said, in America the drinking age is 21 and they seemingly have less of a problem than the UK. So it's hard to deduce much from. Either way, I'm not for a minute suggesting we should apply that same principle to porn. I can't imagine anything worse than my mum sitting me down to watch a BangBros vid.

As for enforcing the laws I don't think it would be that difficult, I think they could create a simple means of verifying age that doesn't compromise the rest of your identity. With all the obsessive "safeguarding" and controls on the internet these days it's a small feature to add. Not to mention that all your info is already possessed by your ISP anyway so it's not exactly a breach of your privacy. If they're gonna kick people's doors down for saying the n word on twitter then they can make porn as hard to get hold of as cigarettes.
