Any chance the drinking age will get lowered to 18 any time soon?

68. isn't any age proffered going to be just as arbitrary?

A restriction on drinking due to age may be arbitrary, however isn't any age proffered going to be just as arbitrary?

We reduce the drinking age to 18, which is all well and good, until someone uses your precise argument to have it lowered to 17, then 16, then 15. 12. Nine... etc. I imagine most people do in fact, want an arbitrary age limit imposed on drinking liquor, the only differences between the standards are merely in degrees, and one may have a rather difficult time arguing the ethical difference in trumpeting the fairness of an age limit of 18, whilst opposed to his neighbor, who turns 18 tomorrow is, for one reason or another denied that same.

"some normalcy to our alcohol laws.."
Specifically who determines normalcy, and upon what objective standard is that measured on?
