Okay, my opinions on drinking ages:
As they stand now, I despise drinking ages. The 21 age limit is a ploy by the federal government to get around the 10 Amendment and ideas of federalism by threatening to withhold money designated to the upkeep of roads. For a while there, Louisiana refused to abide by this and kept its drinking age at 18; its roads sucked and still suck despite giving in. (Side note: the federal government has a drinking age of 18. It is used only on federal property like military bases, if I remember correctly)
Now, if there is going to be a drinking age, I believe it should be decided upon by each state without interference or threats from the national government. I can accept 18 as that as generally the age voting rights, gun ownership rights, etc are formally granted and individuals are no longer thought of as being mindless vessels guided by their parents. However, if parents wish to give their little kiddies a gallon of Canadian Mist whiskey to drink at home, fine by me.
I view the role of government, particularly state governments, as being almost primarily there to protect you and your rights from being violated by others, not to some moral vanguard existing to tell you what you can and cannot do in the privacy of your own home. In many ways, I find restrictions on alcohol consumption, drug use, and even prostitution to be no different than the now unconstitutional illegality of smoking a meat cigar. Now, if you endanger others while under the infulence of alcohol or drugs (or prostitution, I guess, if you’re recreating the car scene from Scary Movie), you are placing others at risk and are violating their rights and deserved to be punished.
So, I guess I’m idealistically for no drinking age at all, but I know realistically that some concessions have to be made. I would be fine with a compromise of states deciding their own ages, and I would be even happier if they decided on 18, as that is seen as the age of passage into adulthood. However, you even drive drunk or commit another crime drunk, I believe you should have additional punishment for having violated others’ rights.
Some European countries, France comes to mind, have a better system with regards to drinking because it is not so despised. I’m sure its populace is taught early on how to respect alcohol. A similar case could be alluded to in earlier American history when guns weren’t so taboo, so the teaching of gun safety was more prevalent. That kind of social structure with alcohol, drugs, and prostitution would be much better than skirting the issue by making it illegal.
And in many ways, I’m not a libertarian. I define myself more as a libertarian with regards to the federal government. I’m not sure how I match up on the state scale. I guess I fit better under the Constitutionalist banner, but meh. One is merely a subset of the other.
