There are many, many things other than Bitcoin which are also guaranteed to be finite in supply (more so in the case of physical goods, since they cannot be forked). BCash, most shitcoins and inactive ICO tokens, for example, are limited in supply in exactly the same way. Share certificates of bust companies are fixed in supply, and yet rarely worth more than the paper they're printed on. The creative output of every dead person is fixed in supply, and yet some dead people's work appreciates massively in value whilst others' is near worthless.
Price is the interaction of supply and demand, and there is no particular reason to believe that people will be more willing to pay over $45k to update ledgers to indicate possession of a particular alphanumeric string in a couple of decades' time than they are now.
