However, you lost BTC. The BTC price paid for said items at the time they were bought is greater than the BTC they have produced.
Well, no, that's false, but hey don't let facts get in the way of a good argument.

I've never bought BTC for fiat, every BTC I've mined has been reinvested or cashed out to fiat.
Well yes. "BTC price paid" is whatever you paid converted to BTC, be it prayers to Luke, or Indian Rubles. So again, yes.
In fact the early Block Erupter boards and AMUs were so over priced that even I (who got an AMU from FriedCat - probably one of the first of anyone not inside Asicminer) have still not made 2 BTC on it - that was the price they were then, though I didn't pay any BTC/Fiat for it, and I expect to never make 2 BTC on it.
Go check again.
I paid for the ASICMiners using BTC I mined using GPUs. GPUs that were sold for more than I bought them for (bought cheap off eBay and sold for more than I bought them 6 months later when more folks wanted those GPUs for mining). So, only fiat spent was the GPUs, which I got back. Power was paid for by fait received after selling BTC.
I have never spent fiat on mining hardware. It's always been BTC produced mining.
So, yeah, just because you suck at mining doesn't mean everyone does.
