To call something a social construct doesn’t diminish the impact of that thing. Race is a social construct as well, and that too has very real impacts on people. Much of what humans interact with on a daily basis are social constructs. That doesn’t make those things meaningless or trivial.

Marriage is a social construct, but that doesn’t mean I can go around acting like I’m single without consequence.

One crime has far less harsh sentences, far less enforcement, and a much more significant impact. Yet harm is the same by the money amounts.
