Right, but gravity well isn’t the boundary where outer space begins. The moon is clearly in outer space, so I’m not really sure why you’d suggest that “within the gravity well” would be inner space. In fact, Earth’s gravity well never ends, it simply diminishes with the square of distance. The entire universe is within Earth’s gravity well, so where would you even put the boundary? Where Earth is no longer the largest gravitational force?

Anyways, it doesn’t matter because as you clearly demonstrated, it can’t be related to gravity.
