Those are useful even for solar colonization. 4 we can't use right now, but 1, 2 and 3 are practical. Sending only female colonizers on Mars with frozen sperm and seed handles population and food production. While robots still aren't autonomous they can be piloted by colonizers to do construction in inhospitable for humans conditions.

We aren't going to go to all that trouble to colonize a hostile planet. If that is the only option we may as well just build giant outposts.

Moon is worth colonizing since we can put our dirty industry there.
Mars is worth colonizing since it can be terraformed and offers passable conditions for long term habitation.
All other options have limited use - research, mining, refueling...
