I feel like I am going a bit off topic here.
As far as I understand there are two reasons, and most likely even more, for the age being 21.
First reason would be to prevent drunk driving, or at least minimize it, since most young adults don't have the same experience with alcohol as
adults. In my home country, Denmark, you can legally buy alcohol from the age of 15 I believe, it was even less when I was a child, your parents can
give you alcohol at any age if they wish, but you won't get your drivers license before you turn 18. We have a very good public transportation system
and our country is not very big, so you can easily get by without owning a car, hence the different approach.
The second reason is that our brains stop developing at around that age, 21, which is why many weed-supports also recommend the same age limit.
However, you need to have a pretty bad alcohol abuse for this be an issue. So I think it is mainly because of the first reason.
So not completely arbitrary.
But laws aren't always right. Which is why we argue about them and need to do so, and whomever gathers the biggest consensus 'wins' (in a democracy at
least). There is no right or wrong, just different approaches and sometimes different intentions.
