Nope. Let's say I'm worth between $10k and $10m, i.e. somewhere in the range of a normal human. I would be crushed by the maintenance costs, even if I kept it

Nope. Let's say I'm worth between $10k and $10m, i.e. somewhere in the range of a normal human. I would be crushed by the maintenance costs, even if I kept it in a Swiss vault instead of on my wall where I could actually look at it. The only reason I would spend 10% of my net worth is to immediately sell it to a Russian oligarch for a fat profit.
