Future me must hate me with all the stuff I leave in her hands. I'm afraid she may build a time machine and come beat me.
Wouldn't she just be risking causing herself more potential issues in her own present?
Unless you believe that by coming back in time and doing that, she would be altering your own personal future, but not hers. (All that Multiverse stuff where every decision causes another reality to be created and whatnot.)
Edit: Plus, what Rowland said. Since you can't create matter out of nothing. Unless you do it TMNT3 movie style and somehow swap places with someone of equal matter, maybe.
