Sounds like 10 years of lock-in to me. The manufacturer will be getting coins until it breaks down or is replaced. Nice revenue stream.
Was than a rebuttal? Any factual points? A consumer is going to sign a 10 year lockin on insignificant NAV gain

There's no signing anything. If you buy a product that lasts 10 years, you won't replace it for 10 years. You have bought 10 years worth of utility in advance.
ASIC mining has only been around for 18 months or so.
2013 seems like 10 years ago to me I guess. It could have been done with GPUs before that. Miners were very resourceful. They didn't find a market demand. Bitcoin's market isn't that large yet.
Correct (although as I said many GPU and ASIC home miners did (and do) in fact view heat as a benefit). Realistically just about any Bitcoin startup is speculation on Bitcoin taking off. I guess the exchanges and a few others might make money before that. Might.
Heating is not fungible with mining.
The experience of GPU and ASIC miners who do this and have done it for years says otherwise.
Your comments about solar water heaters are irrelevant, because people aren't buying them (in the dominant markets). They are therefore inferior in some way (don't work particularly well in built-up cities for example, which is where populations are moving), in the opinion of the people making the purchases. That's the only opinion that matters, not yours.
