Speaking of absurd and foolish, in the libertarian ideologues' quest for imposing their moral-liberalism upon everyone else, perhaps we should abolish voting, too, since Moses never got to cast any vote for who should be the Pharoah of Egypt, nor did Abraham and Sarah get to vote for the King of Babylon.
In absolute hereditary Monarchies, the subjects typically don't Vote.
In elective Republics like the United States, OTOH, the citizenry does Vote.
See the difference? This concludes your course in Remedial kindergarten-level Civics.
Speaking of looking silly, the issue is marriage licenses which the government does issue, not urination licenses which the government does not.
The issue is whether or not the Government should issue Marriage Licenses. Abraham and Sarah, Moses and Zipporah -- all got along just fine without such Government red tape.
