One of the problems I have with the concept of living on mars is the fact that it only has 38% the gravity of earth. How could we manage that without artificial gravity? Even astronauts living on the ISS have all sorts of health problems from just spending a few months up there. In space centrifugal force works, but what about on the planet's surface?
There are two killer apps that will make extra-planetary colonization economically viable: mining in a place that has no environment to harm, and low-gravity retirement communities for the elderly.
If you have the money to retire to Mars, you will be living in rarefied air. Manned space exploration enthusiasm is basically delusional.
OK, when the next dinosaur killer hits, I'll be waving at you from my dome on Ceres.
Then we'll see who has the more hostile living environment.
If mankind is advanced enough to sustain an inhabitable environment on Ceres, I'm pretty sure it won't have much trouble dealing with any large impact on Earth.
What about all the potentially habitable exo planets we are discovering?
If you seriously believe in interstellar travel in any near future, I think it's safe to say you're delusional.

That's like saying aeroplanes are delusional, computers are delusional, the internet is delusional (a person alive 200 years ago would have had no way to conceptualise anything like the internet, or computers, or software, or [insert anything to do with computers here], vaccination is delusional, the telephone is delusional ... I'm pretty sure all this and more was said at some stage.
So the adjective delusional has no meaning, maybe?
If I was telling my family that I plan on building a house and live on the tip of the Everest, on deep oceanic floor or in the middle of Antarctica, everybody would tell me that I'm nuts.
Living on mars is just about as crazy, only much, much more difficult.
If anyone planned any of your examples I'd think it was amazing. The crazy ones change the world - history has shown this repeatedly - that's all I'm going to say!

This movie and others have done a lot to manned space exploration. I'd even say they played a prominent role.
This should make us think, though. Had there not been such a huge SF fiction literature and cinematography about space, people would not give a crap about it, as they would see space for what it is: an almost perfect vacuum, extremely hostile to any life form, where it is very difficult to go and where there is pretty much nothing to do.

Luna and Mars aren't our main concerns... all of our people, and more importantly, almost all of our stuff, is all at the bottom of Earth's annoyingly deep gravity well.
They are concerns if you want viable colonies. In order to get supplies from Earth they are going to have to export useful things back. Anything that makes this cheaper makes the colonies less impossible economically.

Technically not true. The existing materials would just require a stupidly large maximum cross section. Kevlar works for Earth if you don't mind the cable starting out at 1 inch wide at ground level and a mile wide at geosynchronous height.Now, try and image a car capable of riding that cable...

One alternative to the elevator which looks interesting, if mind-bogglingly dangerous (but good god, FUN!) is the space hook. Basically, you're in a special vehicle on the ground, when from the west comes this massive, rapidly moving hook. There is an earth-shattering CLUNK as it grabs the specially designed tether point on the roof of your vehicle, and suddenly, you're not on the ground anymore. The hook rotates around, and flings you off into space. Meanwhile, the other end is back down on earth, picking up another payload.

Kevlar works for Earth if you don't mind the cable starting out at 1 inch wide at ground level and a mile wide at geosynchronous height.Kevlar and similarly strong materials would give taper ratios that are quite reasonable for a lunar space elevator, and only slightly ridiculous for a martian space elevator.
There are two killer apps that will make extra-planetary colonization economically viable: mining in a place that has no environment to harm, and low-gravity retirement communities for the elderly.
Well, asteroid mining is clearly perfect for the first one, but for the second we need low-g ways of getting people into space, first, all current ways are too punishing.1. Expensive as hell, assuming the materials can be found. (see 3)
2. Limited locations to place it - it must be equatorial.
3. Requires cables with tensile strength well beyond our current ability.
Send them up before they get too frail for the trip, so they can live out the rest of their life in the comfort of lunar gravity.
Probably the best bet.

Yes. With a space elevator everything changes. Costs drop and space is accessible for many more uses.
