I don't think it's a crazy idea at all. In a world where the game is all about Astronomy, the bottleneck is Scientist generation, and MoM inherently makes that easier.
Also, the timings for it are better than you'd think. Next turn is 106. I checked in-game, and Calendar would take me roughly 5T to tech - so around T110 or so. Maybe 6T. I eyeballed the Aren settler, and it could plant on the Marble on I think T111 if I counted correctly. The settler completes this coming turn (106), so I have one more turn to consider the idea.

Of course we won’t have OR and we won’t have lumbermills yet if we go through with it, so our Marble city will suck for a while. The city might have to chop a monument and suffer. Not sure.
