He actually made that demand before they illegally demolished it, when the facade was still mostly intact. I don’t think it would have been very practical but still, they absolutely cannot allow the developers to profit from this vandalism.

They should build a mining museum on the site, with a modern but still wonky design (and coins rolling uphill). And force the crooked developers to donate the site as part of a plea deal. It may have been impossible to prove they were behind the arson but a piece of piss to prove that they were behind the illegal demolition.
