You've reversed the directionality: price drives mining activity, but mining activity doesn't determine the price. Miners spending more on hardware & energy won't produce more bitcoins (it just means the difficulty will increase and more CO2 will be released).

I'm saying the fact that you have to waste $10,000 worth of electricity calculating redundant hashes in order to make a bitcoin doesn't mean that bitcoin somehow contains $10k worth of "value" or that the cost of production sets a floor on the price.

People sometimes get confused about this, perhaps reasoning by way of analogy with real-world goods that will (typically) never be sold for less than the cost of their inputs, or they imagine some computerized form of the labor theory of value applies[0], but this is not true. The only factors determining the price of bitcoin are supply (fixed) and demand (driven by speculation).
