There is an enormous amount of concentration now that does't come from pools. This has the same effect of weakening the security model that pools do, or possibly worse (since you can't pull hash rate from KnC if they decide to misbehave).
This is one reason why cloudmining must be avoided like the plague(or possibly exposing you to a ponzi) , and another incentive structure must be developed to encourage decentralized p2p mining.
Switching to an ASIC resistant PoW coin doesn't solve this problem but merely delays the inevitable. As interest and hash power grows ASICS will be developed within time regardless.
This is why their is such a contentious debate between raising the blocksize limit. The people in favor of smaller blocks know the mining is already heavily centralized and that fight may be lost (without a novel solution) and want to at minimum keep node count high and decentralized to balance the centralization of mining.
