I don't buy this. You take the rarity away and make it as common as a common metal you still have:

1. A soft metal (not all are)

2. A high conductor of electrical current

2 will be sought after more and more and more in our age.

It's really not that I care about it being some thing that rappers can put in their teeth but more that it has a use.

I fully acknowledge that having more of it would devalue it, but it's not valued solely on its rarity.
