The point is having all our eggs in one basket is dangerous. Having pockets of humanity existing elsewhere in self-sustaining colonies makes sense for the species. I personally think the next move should be a permanent settlement on the moon where all the required technology can be field-tested and improved but close enough that a rescue is possible if it goes pear shaped. Mars should be the second destination for a colony.
I'd love to look up at the moon and see the lights of a distant colony I think that would be pretty amazing.
