So you really think majority of hash power having full control of the protocol is better then stake holders leading the coin development? Are you serious?
To control the majority of hash power, you must put real resources and might still fail due to slow in movement, it is much more difficult than controlling a few stake holders. Imagine that once bitcoin is becoming POS, then top 10 stake holders will immediately enter the watch list of CIA
To control the majority of stake, you must put real resources behind coercing majority of stakeholders and might still fail due to slow in movement, it is much more difficult than controlling a few mining pools. Imagine that once bitcoin is becoming POOLED, then top 10 pools will immediately enter the watch list of CIA
PoW hash rate domination are all temporary and can be changed quickly, we have seen many times old hash rate king been knocked down by new mining pools/farms

Enjoy your new masters.
This is for PoS coin stake holders

Are you telling me that you don't think the NSA could destroy Bitcoin right now if it wanted to? I hope you aren't this naive. You don't really think they spend $80,000 on a toilet seat and $50,000 on a hammer now do you?
