Interesting post but i have a few points to make.
Everything you have said about the moon is purely speculative and in essence, is on the basis we have really been to the moon and all information learned is correct.

Now without jumping down that rabbithole of conspiracy, we would indeed still have major problems with the space travel passing through the van allen radiation belts and even then creating infrastructure that could make a vestige haven for humanity on the moon.

The ISS after 16 years can only house around 6 people at maximum, so how could we build and maintain a crew on the moon with no atmosphere to make a base that would support humanity ongoing?

To me, its an impossible task and we would require a destination that is capable of supporting h2o naturally and an environment similar to earth to survive. Its just a pipedream otherwise and no technology is sustainable on the moon apart from a hollywood perspective but just wont work in reality ever.

I will eat my words if proven wrong but we havent even been outside or able to go beyond low earth orbit in over 40 years and thats if you believe we ever did.

Sorry to be negative on your post, i just think we are subject to a lot of mind control through the media!

Mars is the destination and makes much more sense to start an offworld colony to protect the human race from an extinction event.
