I would agree that any notion of a large martian settlement (much less a comfortable one that people actually want to live in) on any shorter timeframe is not realistic and that Mars cannot be treated as a "plan B" in the case of climate change making Earth uninhabitable, but total dismissal of the idea (as well as the idea that humans will forever [and potentially should] be permanently Earth-bound) rubs me the wrong way.
Yes, it's an unfathomably difficult and complex project that should not be in any way underestimated. Realistically, it will take many decades at minimum and probably in excess of a century. That doesn't mean it shouldn't be attempted however, and it's not as if any of it will magically get easier in all the time spent not trying. This could wind up being a self-fulfilling prophecy sort of situation if it's allowed to be.

I think you've vastly underestimated the difficulty and the timeline, ironically. It's unrealistic to use the words "decades" or "a century". On the contrary, that's the delusion.
Consider: more than 50 years after putting a few people on the Moon very briefly, we're no closer to a colony on the Moon. And rocket technology won't help at all. Among the problems: the Moon has very little gravity, and we can't handwave like Q, "just change the gravitational constant of the universe."
I is lot less question of can we, but should we. The amount of time and resources needed are most likely so extreme that most other use cases would be better.
Sometimes it make lot of sense not to even try. I mean technically we could save a few lives in northern countries during winter by heating all roads in such a way that there is no ice or snow... Doable maybe... But not worth trying...
