The real mona lisa has massive real-world value. You can get a copy of the mona lisa that the average person can't distinguish between for $10.99, and yet that copy in no way reduces the value of the real mona lisa (if anything it increases it). Things that are intentionally non-fungible don't care much about being copied, as long as you can always identify a copy, at the end of the day it's mostly a status game. But status games do have real-world value.
