In my opinion, being responsible with alcohol requires experience, which we all know is acquired through trials and error. I share the controversial belief that parents should be the ones to responsibly shepherd their kids' drinking habits. They shouldn't just wait for them to turn 21 and discover it in the "wild", or worse, let them go in those popular drinking safaris in Canada or Mexico, where the legal age is lower and regulations somewhat more loosely applied.
You often find more police stations in places with more crime. Does that mean police stations cause crime? I doubt it. You could argue police stations cannot reduce crime to the levels of lesser crime areas but you cannot say that police stations are the cause of crime. The reality is: there is crime so you build police stations, not the other way around.
I believe this is the same for alcohol regulations. There are a lot of alcohol abuse so they make alcohol regulations stiffer. It may be true that regulations does nothing to reduce abuse and actually cause people to abuse alcohol even more but there is no evidence to prove this unambiguously.
You have an interesting theory, I'll hands down give you that, its a compelling perspective and I've never heard our nation's alcohol relationship in those terms, but that having been said, I feel like our nation is one that historically has overestimated our problems with alcohol. It may be a response to prevalence, I'm not going to take that away, but there is also the factor that we perceive the same prevalence differently.
I grew up near the Vermont/Canada border, the first time I went up there to drink I was 14 and we were raging it hard in some Quebecois' basement. I went upstairs to take a leak and almost shit a brick because unbeknownst to me, their parents were chilling upstairs watching TV and were fine with the fact we were getting wasted and hooking up in the basement. One of the girls that had gone up to cananda with me was puking her guts out in the basement bathroom and refusing to speak anything but broken French and they were completely fine with this. All the Quebecois' parents knew they were off getting trashed and were fine with it too, hell the mother of the family me and pukey mcgee were staying with us bought us our booze. A few years later I had a handful of friends at my place in the states and we had a few shots in the attic over newyears. My parents found and were pissed, my, and everyone that was there's, parents yelled at us quite a bit.
So we might have more abuse here, but we certainly define abuse differently.
Only once in my life have I ever drunk so much I threw up. And that was on my 25th birthday when I got a bit careless.

There are other reasons why "binge drinking" appears to be higher in anglo countries (US, Britain, Canada, etc...). Especially among the upper middle class. Longer work weeks than the rest of the industrialized world, less vacation days, etc... Drinking age may play a role in our propensity towards binge drinking, but I think it also has a lot to do with our "work hard, play hard" mentality.
There is another angle to this though - is it better to engage in binge drinking right in the middle of adolescence, when the body and mind is at a rapid pace of development, or in your twenties, when you are physically better equipped to deal with the effects of excessive alcohol consumption?
I am not a medical professional, but instinctively, the second option seems to me to be the safer one.
Why would you believe that? I don't have any specific knowledge, but I also see no reason to believe that you're better equipped (physiologically) at 25 to handle alcohol than you are at 15.
European teens do drive - but it's not fashionable.
USA teens _have_ to drive. The party is spread out (multiple locations in suburbia) and the vehicle is the symbol of empowerment.
Obviously, mixing heavy or inexperienced drinking with driving is a recipe for death.

In short, it affects spatial working memory, verbal encoding and ability to inhibit ourselves. These effects don't seem that nefarious, and not so prominent in affecting our lives in a significant way; but don't take my word because I'm no neuro scientist.
On the other hand, on personal experience I've seen greater social issues with people that are heavy drinkers in their post adolescence period.
I've also found myself drinking more, like having a pint or two several times a week. One reason is because there are so many good ales here, but also the weather and winter darkness makes it more appealing. It makes you feel warm and cozy somehow, where by contrast, drinking on a sunny beach makes you feel light-headed and exhausted.
For example I weren't drinking till 18, because I was very religious in primary/secondary school, and priests encouraged promising to yourselves to never drink till 18. Most people didn't care, I did (religion is nice mind-hack, btw, it's a shame it stops working when you don't believe it anymore).
So I had to learn to party without alcohol, and I did. Some people were unfriendly because of that, but I figured they were obviously dumb, if me not drinking spoils their fun, so I won't care about them.
Then I got 18, go to university, and drink alcohol like everybody, but never feel the need to drink too much. As for now I'm 28, and I've never had hangover, or lost memory. And I was partying hard at university.
In my country you can buy alcohol from 18, but enforcement is not very strict, so kids start drinking in primary school, because it's cool, because you're gambling system. Of course most people grow up eventually. Binge drinking is a part of culture (well, wódka is Polish/Russian invention :) ), but young people prefer beer, and you have to really want to got drunk, when drinking beer, to got drunk.
I think it more depends on the attitude and example of parents (mine had drink on occasions, but I've never seen my parents drunk. They also never made the alcohol sound like it's some great forbidden fruit they had to protect me from).
Now we have to question the cause/effect relationship. Do we have higher age limits because we have alcohol problems or do we have alcohol problems because the age limit is high?
My parents allowed me to have a small sips starting when I was 5. At that point in my life, I could not understand why adults wanted to drink such awful stuff when there was sweet soda. My parents have never said NO to me when I asked for alcohol.
Result? I learned that alcohol is something you drink in moderation, I've never been (really) drunk, I've never associated alcohol with rebellion or a necessity for having fun or having a diner.
Also, some people have addictive personalities (in addition to alcoholism).
In my home country (Austria) I could buy alcohol at age 13 without any problems. No one would ask for an ID. I think nowadays they are a little bit stricter, but you are still legally allowed to buy alcohol once you turn 16. Once you turn a little bit older alcohol isn't that interesting any more. Of course, you'd still buy a beer (or more) if you're partying with friends, but getting totally wasted is something teenagers would do.
I've moved to the US some time ago, and here I have the impression that even people in their late-twenties get regularly drunk just "because they can" and are "allowed to do so". Seems they just never learned how to use alcohol responsibly while they were young, and at some age it's too late to learn it.
