In the sense that we need to remove our dependence on a single-point-of-failure planet to avoid existential risk, then I agree that terraforming is ultimately desirable. But entire planets claimed by crushingly authoritarian political systems or uncontrolled profit-seeking corporations doesn't seem like a great way to safeguard humanity either. What do you want terraforming for?
