While Industrialization does not equal Centralization; it does certainly help because of the simple fact it prevents the small guy to contribute. That said, there's is no way of going forward without some degree of Industrialization. Saying No to Industrialization is only an idealistic and romantic stance at most.
However, the fact is we are already having centralization problems (GHash.io is the largest pool, with proven dishonest behavior, and borderline-scam prices) so this is a topic where serious thought needs to be put by those with power and control. It is in their (and everyone else's) best interest.
Too many to quote so I just picked this one to start from.
Preventing the small guy to contribute => So is this Wall Street 2.0? That is what it sounds like. Oh here, we'll let the barons take this over and run with it, but we'll let them make stuff like ShareBuilder and AmeriTrade to tax people into, inside of, and coming out of the system. Oh wait, we already have that, we sell shares and folks take management fees, it's what the Group Buy section has turned into. Scale it up, this is where mining is going apparently. And we've seen how well buying shares in hardware and hardware/mining companies has worked out so far.
De/Centralization => Hundreds or thousands of AM Containers? Are you kidding me? Let's bullshit with some numbers and say an AMC (AM Container) produces 100TH. We'll go balls to the wall and use a Genesisblock guesstimate for diff and say in April, trimming numbers down, diff will be around 8.5b. Just for reference, if the KNC Neptune ships in April (in their nice six month window) for the previous-customer price of $10k,
it will never break even. So we're rolling out AMC's, KNC is rolling out Neptunes, a few others may have gotten their act together and started shipping as well. Rather than adding 100-400GH per device we're starting to crank out devices by the TH. And with multi-TH devices you have larger power requirements, ruling out anyone who rents, students, even some homeowners.
Sadly the more I think about it and conjecture with other business friends the more we agree the ship has already sailed for mining. It isn't even a race to the bottom, it's a down and out death march and is being led by AMCs and Neptunes. And unfortunately, per what Voodah said, I doubt those with "power and control" really give a damn about this. They're all chasing the dream, but in this case the more dreamers (vendors) that win the more everyone loses. This time next year a 100GH device will be akin to an AM stick in terms of BTC generation capabilities and we'll likely see a severe drying up of custom hardware, aftermarket sales (read: ebay, amazon), group buys, you name it.
