I don't think curses or at least curse-like effects need to be impossible, if you're a unicorn. Seems obvious that Twilight could do a lot of things that would seem like a curse to the recipient.
I think when the ponies talk about curses, they're talking about magical-like effects with a non-magical origin, and that's what Twilight is or should be objecting to. If she's objecting to the effects themselves being impossible, then she's just plain wrong.
