No. Ethereum is the World Computer. We do everything, and we do it better than anyone else, and we do it trustlessly. Finance, payment, and shared state of the open world can all exist on the World Computer.
Ether is an application of the World Computer. It is the greatest store of value and by virtue of existing on a World Computer the greatest source of trustless collateral for the greatest DeFi protocols making the greatest money in the world.
We don't need to choose one or the other. We never need to choose one or the other. We eat this cake and have it too. We're allowed to win everywhere.
