Sure, but someone else could pretend that they were you, with your DNA. They'd need to fake the "fresh sample" part, but that's doable.

Of course, they take a hair from your head; and it was exactly the fake hair they had prepared, and then they take a drop of blood from your finger; and its the fake finger you prepared; then they check your iris and its the eye transplantation from the victim just like you prepared.

That's a good point. But I still don't like it.

I mean, there are circumstances where it'd work. But the requirements for verification and chain of custody would limit usefulness, I think.

Yeah, trust companies like Equifax instead.
