I would point out that even with
free hardware, $0.10 electricity and <1W per GH the exchange rate would need to be $42,860 per BTC. In other words miners would be paying $42,860 in electricity (or more if they have less efficient rigs) to mine one BTC.
Awesome analysis.
I do not understand why you bother with the sarcasm. It will be lost on them. No one is going to read the long string that you put up that had thoughtful analysis of where the network could go based on marginal costs and highlighting how the pre-order process effs up rational economic decision making. Stop wasting your typing. Let them use their website models to explain everything to themselves. A great question at HBS in first year finance for modeling "If you model a company growing at 6% per year and USA GDP is growing at 3%, how large that company become over time?"
