"Pooled staking" isn't required now in NXT nor will it be required in the future
You can stop repeating the same lie over and over NXT shill. Since other people are going to be pooling stake for frequency of payouts in the endgame of standard PoS, the act of them doing so makes it harder for you to solo stake (more like impossible), thus forcing you into pooling stake as well. The general public is not going to stake with frequency of payouts set to like once every 10 years. In that situation, either everyone will pool stake, or very few people will stake at all except for the largest holders (banks).
Collusion doesn't affect PoW or PoS like it effects DPoS. By removing the requirement that miners/forgers purchase hardware/stake and replacing it with a corrupt voting mechanism, you have made it much easier for a small group to control the entire network by controlling the delegates.
PoW, PoS, and DPoS are all more similar than they are different. You're trying to twist things around while shilling for NXT and pretending that only DPoS is an aristocracy when both PoS and PoW are as well. Anything where you derive power by how much stake you hold is an aristocracy. PoW is an aristocracy because nothing else matters besides what the richest pool operators do that hold most the hash power. Standard proof of stake gets hit with a double penalty of aristocracy by giving power to stake, then by having centralized mining pools on top of that. It's easy to see that standard proof of stake has the negatives of PoW plus more new negatives at the same time.
Economic clustering isn't needed now because the network tps isn't high enough. Just like DPoS isn't needed now because your network tps isn't high enough
This is the first time I've ever seen someone try to turn a product deficiency into a feature. Nobody will use a decentralized exchange with 1 minute block times when there's one with 3 second block times out. The real reason transparent forging isn't working in NXT is because they're unsure how to implement it properly.
