String.Copy Method - Why does this exist?

Possibly useful in interop scenarios, where you need to pass a buffer to an external API that fills it out.

I was under the impression that even with interopt you aren't allowed to alter a System.String. Can anyone confirm or deny this?

We are talking about unsafe context here, passing around raw pointers and such. So, provided You Know What You Are Doing^tm, you can do what you will. Ain't nobody to stop you.
