Well, I believe finite supply is like a stamp collection. It's "collectors item" in terms of economics. It will lose its fungibility in time and people will want to have bitcoin because of its rarity. It's perfect for store of value, but it cannot be used currency of modern world just because of "right of economics". You know that guy who is a stamp collector and burnt his one of high priced stamp, and consequently second one's price went to the roof.

Monero can be a currency of an utopic world. However, we are not living in an utopic world. It won't be used except privacy enthusiasts, criminals, some wannabes and Linux cowboys in the future, I'm afraid.
