Sorry, the brevity of that comment apparently didn't convey my point well enough. Real estate is an example of what you theorized would happen with coffee beans. It is a useful resource that is also used for speculative investment. It is something everyone needs, but as a society we have decided its price should also always be increasing. This has a net negative impact on society.
Bitcoin existing doesn't stop people from speculatively investing in real estate, so I don't think people will just start speculating on coffee beans or something similar if Bitcoin goes away.
