Wouldn't work. If there's so many diamonds, they'd just kind of lose their value. Also, who are you gonna sell them to, if everyone has them?
Although it could kind of be a new currency that excludes the rich, making their wealth at least a little useless.
I fully agree on the premise, but I think it needs refining.
I don't plan to use them for wealth, it's just a nice stable form of carbon that's sharp and heavy.
Agreed, but looking in the bright side: it would kill the diamond industry, which is a fucking awful blight on the world :)
