As you say the mission location does not even spawn until you "warp" to it. I always assumed it is simply an instance, not really a persistent location. If it was a persistent location, then a wandering ship could hypothetically travel to it without warping. EVE avoids this by making distances to vast that this is probabilistically impossible.
The mission sites are not instanced, and although as you say the distances are so vast you'll never stumble across one, they can be scanned out and intruded upon. It's actually a known (and controversial!) playstyle, google for "EVE ninja salvaging" if you'd like to know more.
