Um... after learning physics you literally unstoppable. You could make it so anything traveling above a certain threshold would dead stop if it got near you. (bullet/missile proof)

Even then it'd be scary, because you define it in a mathematical way. It's very easy to make a mistake. Programs always have bugs, but your "bugs" could destroy the universe, or at least yourself. Very powerful yes, but you have to be very sure of your equations. And whatever you do: don't divide by zero!

Simple solution. Just never use it. Nothing ventured, nothing lost.

Well, you could raise an island from the ocean floor if need be. But it occurs to me that the literal reading of this specifies a "patch of land", so it makes sense that the random location would not be in an ocean or lake.
I found a website that serves up random locations on Earth and kept clicking until the first one that was on land. I got a spot just inside the northern edge of Bandingilo National Park in South Sudan. Looks like a pretty nice place, and not too hard to get to (I'd hate to have hit a spot in Antarctica or the heart of the Sahara or something like that). The local political situation could be a bit tricky, though, South Sudan is wretchedly poor and wracked with civil war. I'd probably want to keep a low profile.
