being a 2+ planet species wont help local overpopulation. it is too much more effective to ship a highly diverse sampling of frozen sperm and ova manufacture most of your people onsite. Moving that many people just does not make sense when you have more cost effective alternatives. plus adding planets inside the solar system only gives you 2 real targets (mars and venus) mining asteroids to build spinning habitats is a much more viable colonization target.
