I've made a valid point: why should ASIC vendors sell ASIC's rather than mine with them? The only reply I got was a long-winded
waffle that strung several half-arguements together.
No, several people have explained this to you, in several different ways, and you still don't get it. Whether you physically can't understand, or you're just too damn stubborn remains to be seen.
Point 1) All manufacturers have stated that they will not, under any circumstances, mine with their hardware before the hardware gets shipped to customers.
Point 2) If BFL brings online 150TH, they would be >80% of the network. This is the exact opposite of the decentralization that makes the network secure. If one party owned 80% of the network, even for a brief period, faith in the network would crash. Sure, they could mine for a month straight at 80% of the network hashrate to mine the 75,000 coins it would take just to equal the $1million in preorders (at today's prices), but by the end of the month there would be no Bitcoin network outside of BFL, and those coins would be useless - literally worth pennies, if anything.
Point 3) Even if BFL only brings online 10TH/s to avoid total network domination, it still doesn't make much sense. Sure, they'd be mining ~1000 BTC/day, but that's only ~$13,000. Compare that to the $1million+ in preorders, and it still doesn't make sense to mine.
Point 4) The first manufacturer to start shipping ASICs, and proove that they can deliver a product within advertised specs, will get a lot more pre-orders from those who are caution or even doubters. They actually have a monetary interest in being the first manufacturer to ship.
Other people have made other points on top of these, but you refuse to listen. Just because you can't see past your goose-and-the-golden-egg analogy, doesn't mean it makes sense in the real world.
