Do I HAVE to get disability insurance?

I know disability insurance is important and that you can't predict what could happen in your life and to your health. Most attendings have told me to get it (except one radiologist I know who said it's not necessary until later in life when I have a family to feed). But just wondering if there are people out there that didn't get it, and what was your reasoning? I really don't want to get it but I just feel so pressured.
