I would have some serious questions about a lunar habitat situated in a natural "cave" or lava tube on the Moon.
How stable is the roof? Has that stability assessment considered the thermal and chemical off gas effects of the habitat on the surrounding rock material?
What is the backup safety plan and equipment if that assessment is flawed?
Remember, the Japanese assessment of the "maximum probably tsunami" at their Fukushima nuclear power plant was "flawed" so badly that they melted fuel in several reactors when the actual bad tsunami happened and exceeded their calculations.
When a habitat on the Moon fails, there is no place to run to, and nobody there to rescue you.
