That's a good point but Monero is a currency, not a treasure, so I think, that won't work. Who needs XMR when it's hard to convert it into fiat or pay for services with it?
There are services that accept XMR, either only XMR, or multiple cryptocurrencies and XMR among them. So, who would need XMR in this case? Someone who would like to pay for the service and maintain their privacy at the highest possible level.
If there are no services to accept it, then it will be limited only to those who will keep it and use it P2P for other types of financial deals (legal & illegal).
In general, it all depends on the demand, I guess.
