I don’t think the author understands how expensive construction can be. Those millions MC has to renovate the place would not even be close to enough for that amount of work. Maybe it’s enough for one of the 5 projects, but even then not likely. Especially if he blows most of it on luxury materials (which also don’t automatically become something you can use in construction)
This whole thing about precious metals and jems is stupid. They would be for investment when the markets recover, not for building. Nothing would be made of gold and jems. Those would be ascents. Precious woods would be a better investment for interior designs. The majority of the consternation will be iron, steel, and cement.
