Interesting.  I try to present a similar concept when I get asked about operating expenses (hardware, power bill, etc.) versus BTC mined.  For example: if mining one BTC ends up yielding a negative bottom line of -$100 (technically a loss) after all the operating expenses are applied, it can be argued that it is akin to buying one BTC at $100.  Therefore, based on the current BTC-USD average exchange rate of $138, it would then be an excellent buy.  It's all relative.
