While probably true in general for this board, and I agree this 'should' be true, it is, in fact, a myth. The Federal law (23 U.S.C. § 158) specifies bans on 'purchasing' and 'public possession' under the age of 21. It doesn't address under age consumption at all. State laws vary, and some extend it to a ban.
There are 6 States that explicitly state a ban on drinking under the age of 21.
There are still about 8 States that allow consumption under 21 when at home or supervised by consenting family members.
Of those states not included in the above 2 groups, most make no mention of underage consumption and defer to the Federal law.
And you can check to see what your State says on the matter of homebrewing here:
