That consequence doesn't follow. Capital intensive mining does not make the blockchain any more decentralized, as long as miners doesn't collude enough to form a single majority. Game theory suggests that financially motivated attackers would do best to avoid that however. Even if ASICs were not mentioned by name, Sastoshi wrote about how mining was expected in the future to be the work of large bank-like organizations, but apparently did not worry that this would harm the project. What he may not have foreseen was the emergence of mining pools, separate from miners themselves, that in certain ways can behave like cartels. That could have been avoided with a mining pool protocol where miners are the ones to form blocks, but the software included no possibility to pool mining power at all.
