i.e ASIC manufacturers will do what is in their best economic interest.
Would anyone like to offer a reasonable and succinct refutation of this law? No prizes from tangled specuation about how "everyone will drop bitcoin" and
such witchcraft.
I see where you are trying to go with this statement, but I must say that it a very strange statement. Personally, I believe that:
"An ASIC manufacturer will deliver an ASIC when it's available and for a price equal to the average customer's expected bitcoin revenue for the number of months that the average customer would consider reasonable for paying off their equipment."
For example if an ASIC manufacturer has the technology in hand and their average customer expects to make 10 BTC/month and is willing to accept a 1 year payoff on the equipment purchase, then it would be reasonable for the ASIC manufacturer to sell the product to the public for 120 BTC.
With this logic, it is perfectly reasonable for the ASIC provider to sell the ASIC instead of mining with it themselves. Why bother mining yourself when you can capture most of the expected revenue upfront and let someone else do all the work and take all the risk?
