Astronauts could use their own urine to build moon bases one day

this stands to reason of a sort, if i remember right the Romans used pig blood (we hope) to mix in to their concrete to make it set up under water , a similar process with urine or perhaps chemicals found on the moon or mars might help to make stronger structures we need to be doing comprehensive analysis of the available chemicals and how to extract them now before we try building on these hostile environments

It would take a lot of urine to build up structures like this. It would seem a lot easier just to take urea up in bulk then relying on people peeing into a "community urine jug" to slowly build up the structure.

Better idea:

Don't send humans at all since they are so costly to maintain. Do everything with robots, which are 1000x cheaper and can do just about everything people can. With all the advanced electronics and sensors being developed, the robots would be equally successful at returning data and material from the moon than any manned mission. Keep the cost low, and use all those spared funds to deal with all the problems on the moon's neighbor, Mother Earth. There are a lot of problems on Earth, in case people haven't been paying attention.

Humans on the moon - been there, done that!

and when we have another 5 billion people where do we put them or feed them getting colonies on other worlds is the only way to solve the problems. just try and tell a catholic they have to practice birth control

Let's see what our options are:

1) Go to distant, totally barren, hostile planet with resupply depending on another distant planet. That distant planet is going bad with over -crowding (as noted above) and will likely give you up for lost over time - so no hope of surviving long-term on barren planet. (Please don't respond with terraforming and other idiotic notions vastly beyond our abilities. I see enough of that in sci-fi movies.)

2) Stay where you are, spend money on remediation and/or let mother nature take care of over-crowding etc. and hope for survival rather than going to distant barren hostile planet and assure your demise.

Tough call. I will go with # 2.
