I’m willing to wager that by the time we are concerned about finding homes for another full earth load of humans we will be spreading out far beyond just the Moon and Mars. And, as part of an effort to “back-up” humanity that is a good thing. We should be on many, many planets and in many solar systems. To that point. If one of these habitats is built the first ones should serve as transit vessels to nearby systems, with the final destination of its crew being a planet. Additionally, let’s take Bezo’s own logic a step further. When gravity levels are less than that of Earth, say, on the Moon, we we’ll be able to build much higher with greater economy. And we will be able to build into the Moon with greater economy as it is 60% the density of Earth. This effectively increases the livable area, if we are to count “engineered surface area”. The same is true of other planetary and Moon surfaces in our solar system. You once again are left justifying the effort of building the habitat instead of extending the pre existing available planetary foundation
