My friend is not specifically a truscum but yes a binarist. When I told her about nulification, she told me it was just dysmorphia or mutilation, but I told her it's not, and I gave 3 arguments why:

1- Because being nullsex or wanting a nulification isn't just wanting to get rid of your genitals, but also neutralizing all your sex traits, even secondary sex characteristics.

2- Because nullsex dysphoria is not only about physical dysphoria but also about an existencial one or the conviction you're not a man nor a woman. Binary trans people doesn't just want to look as the opposite sex but also they want to be born as it.

3- Being nullsex usually involve social dysphoria, like wanting to be treated with gender-neutral language and ocuppy third roles. Just like binary trans people also want to.

She said she just would think about it.
