The problem is that Bitcoin itself is not natural. As I have said elsewhere (and been attacked by assclowns of all stripes and denominations, lol), Bitcoin, in this aspect, is no different than any other fiat money out there (or currency, if you please), my point being that mimicking scarcity (or any other quality) of its counterparts such as gold doesn't endow it with the resilience and robustness due to their inherent value (entrenched deep in the minds and nature of people)...
Beauty is in the eye of the beholder
None of the money is natural, even gold has to be coined into unique form and weight to circulate as money. People usually do not accept gold bars/nuggets because they can not tell the purity without professional equipment. Then the trust falls on the quality of those gold coins and the issuance of those coins, so they are usually made by authorities (gold smith centuries ago then later coinage organization). That's the key to money's value: An authority that people can trust
Using gold as money is an effect not a cause of gold's appeal to people. Bitcoin, like other fiat monies, doesn't have this attractiveness through its own existence per se, i.e. beyond the function of being money. In fact, its very existence is a result of deliberate conscious effort...
That was my point (natural vs artificial)
