A "functional" independent civilization on Mars is a long way (millennia) off, and not really relevant to the topic of the video. Cody is advocating for a ban on all human Mars missions, even short term research missions. I'm not sure that this is feasible, reasonable, or wise.
I would encourage the use of a stronger term than “let”. The sooner that they can be forced to bootstrap themselves up there en mass, the better. And if their crappy tech fails in them just outside of warranty (space suit warranty limited to Earth orbit, do not expose to harsh conditions/full vacuum/human urine/martian dust. Glass cover not included), well too bad.
Why do you think so? I mean the office at NASA exists with a publicly available description of what it does, do you disagree with having someone be there to oversee adherence to the rules and be responsible for them being adhered to?
