Actually with CS stuff there's scarcity too, but since it's digital it's easy to change. Same with designer bags (nothing stopping them from churning out more, but they choose not to do that). Not so with vintage items though, since they're no longer made.

But a lot of Stuff is made with future vintage in mind, e.g. every Ferrari or other high end sports car will only appreciate in value.
