Not “all that is required by the Constitution” - it is all that is permitted by the Constitution. The Constitution is a grant of express powers. Congress doesn’t gewt to expand them. They have the right to direct how the enumeration shall be executed and nothing more.

Excellent, someone who gets it. The very foundation of the Constitution makes it contradictory that it would require that individual citizens submit to enumeration. It permits the Federal Government to enumerate the population. Or, I suppose you could say, it states a duty of the Federal Government. In order to affect correct representation, I will answer the question of how many live in my household. But nothing more.
