One must simply gaze upon the glory of The Cube. The Cube will invite you in, keep you warm, keep you safe. The Cube welcomes all. The Cube just wants to share.
I mean, I can only estimate it's size from the person standing next to it. From there I can use that estimate to get the volume of the cube, then the weight, then look up the cost by weight right now and apply the average.
I'm betting I got it a few months before someone can gather the equipment to steal it. It would have outlived its novelty and likely be a burden at that point. If the cult works out The Cube should be self sufficient and could even become a profitable local attraction.
