Wat? If I'm buying a bitcoin, why would I ever pay more than it would
cost me to mine one?

This is almost content-free, but what content it has seems wrong. The
upper value of a bitcoin is bounded by the cost to produce it. The
cost of producing a bitcoin is the current difficulty * the cost to
run the latest rig * the number of peope-running-latest-rig
equivalents who are currently mining. Two of these quantities can get
(almost) arbitrarily small. So, the value of a bitcoin can get
arbitrarily small - but not because it is an entirely separate
