PoS would eventually concentrate control to a group of major stakeholders and then no amount of innovation will be able to change that. If it's not immediate, then it's the end game of this model.
This is a REALLY good point. Even if PoS could "save energy",
do we really that kind of system?
Yup!
Let the kings compete for control, while people compete for profit.
Seems pretty balanced and fair to me. This way no one gets bored and turns to evil
The law of conservation of energy would make sure that no energy is "wasted" in the process, just transformed.
I have been highly critical of PoS in the past where large stakeholders are rewarded based upon forging unfairly benefiting the wealthy. This has nothing to do with the conversation though as I have already clearly expressed a prohibition upon any changes that increased centralization and rewarding the largest stakeholders for doing nothing would not only lead to more centralization but present security risks to Bitcoin.
The algo can be designed where the largest stakeholders don't unfairly benefit from sitting on their bag quite easily.
