Regarding the “breathable air”, where’s the nitrogen and carbon dioxide going to come from? Pure oxygen is not an option. IIRC there’s only trace amounts of carbon in moon regolith. So if you want plants and an artificial biosphere would you have to bring it all with you?

Do you really need much nitrogen? They used pure oxygen on space missions and other than the catastrophic problem of fire, astronauts breathed it okay.

Might have problems long-term though.
