it's not clear we are rich in resources compared to the typical exosolar system. Maybe 50% of all stars in Milky Way may have one or more planets in orbit, There may be many more fre floating rogue planets than there are planets bound in orbit around stars. So it seems to me the notion that our solar system is strategic for resource or positional reasons is dubious.
Also, that colonization of space consist of going from habitable planetary system to habitable planetary system in an effort to recreate many more or less faithful replicas of the conditions on the home planet during pre- or early- industrial days is a common Sci-fi troup, but I suspect that is too reliant on our current mode of existence, and not reflective of what would be convenient to a truly interstellar civilization that can muster the resources to colonize on a large scale.
