I think the premise is still quite doable, especially if there were some condition on Earth which prevented agricultural production from reaching its current capacity.
Anything that would leave spaceflight-capable civilization standing would also leave Earth better suited for food production than the Moon. It's an absurd premise, and any attempt to justify it with actual logistics will simply draw attention to it. Just imply the situation is due to "corruption" and leave the details to the imagination of the audience.
