As people are saying, sometimes you can't have your cake and eat it too. The way I am seeing it is that Ethereum developers and Vitalik Buterin have to decide a balancing act taking all considerations and concerns on the table as they decide on how to tackle best the pressing challenges of the network and to make sure that it can respond well the things of the future. Will staking be affecting the price of Ethereum? Of course, it can affect but as to how pervasive or extent that is the question hard to answer. Will staking not jeopardize Ethereum as a payment platform? Well, it got a bigger supply than Bitcoin, so I think this will not really be a big factor. In fact, if they can make the network unclogged and as fast as it should be then that can help a lot for mainstream adoption and for merchants to adopt Ethereum. I am on the side of the people who believe in Ethereum, the same confidence I have for Bitcoin. I don't believe in monopoly though too many players can also hurt a bit.
