Unless you have a septic system, numbnuts.
How serious, really, is this problem of frozen pipes?
I'm not being silly; I've just never encountered frozen pipes before.
I spent my childhood in a great big huge old house larger than a barn, my adolescence in a somewhat smaller house of brand-new construction, and my college years and afterwards in rented places, both apartments and houses. In Nebraska, Pennsylvania, and New Jersey.
The plumbing of course was different in all places.
However, I never had to deal with frozen pipes, and I don't recall that when I was younger, adults had to deal with them either.
Have I just been lucky, or is this, really, an exaggerated problem?
