A lot of people would like to live on Mars, given the chance. Meanwhile, people are growing richer and technology is advancing. It's fairly likely that at some point there will be a point where people can pay their own way to creating a Martian colony.
A lot of people might like the idea of living on Mars when there is absolutely no risk of that actually happening. But
really there is not much point in living on Mars for extended periods of time, there's very little that humans could do that machines couldn't do as well and a lot cheaper. Combine that pointlessness with what would in practice be an an isolated, risky and uncomfortable life, and I suspect that the pool shrinks down dramatically.
