I think the security is actually pretty good on the other space bodies, provided the colony is self-sufficient and does not depend on supplies from Earth. Mars is better then Moon though.

The modern space rockets are slow and easily detectable, and I am sure that if one could get to the moon, and then wanted to build a system that shoots them down, they'd be able to. Especially given that moon-based interceptors will have much smaller gravity well to worry about.

Another argument is that very technically complex products, like space rockets, require a complex society. So if Earth falls into anarchy, there is a good chance the supply chains would be disturbed enough that no one could build multiple space rockets full of bombs even if they wanted to.

You realize that any failure of a life-support device (air containment and renewal, water storage and renewal, heating) means you're dead before anyone can send help? It's like being stranded on an inflatable boat in the middle of the ocean: one tiny hole you can't fix and you're dead.

Please tell me how your colony is going to manufacture the semiconductors it relies on in a self-sufficient way…

> So if Earth falls into anarchy,

That's the opposite argument from the one you made above (“Some people might wish to rule all of humanity or convert/exterminate all heretics” is the opposite of anarchy!) and in that case you're as safe on Antarctica from a military perspective.

> there is a good chance the supply chains would be disturbed

Which means death in medium terms, because as I said above as no space base can be self-sufficient (heck no country on earth can be self sufficient in the modern world already, how do you expect a small spacial colony to be better at self-sufficiency than China?!)
