I would normally say that a valuable asset that goes a year without being used isn't really lost when it goes missing.

It's like a mining company buying a plot of land that they know has valuable minerals on it for the sake of sitting on it to make their other plots more valuable. It's the exact position I think governments should tax/seize to the point that it is inefficient to sit on.

Thankfully these situations are rarer and rarer with the sharing economy allowing illiquid assets to actually be used for their intended purpose when not used by their owner.
