You have to add the cost of the armed guards, because a big block of gold will be a nice target of a robbery.

Well, yes. To be fair, if there was like a farm of these devices, it might makes sense to swallow that expense.

I wish gold wasn't so rare! Its such an amazing material, and our economy is not based on precious materials anymore (except the commodity markets or course), so it seems like a really sad thing that we can't have more abundant gold just yet
