This is too high a price for Ethereum, even if he switches to PoS he will not be able to grow so much. Moreover, it should be borne in mind that with such a high price of ETH and the current value of gaz, the price of one transaction will be 20 times higher than now. Perhaps the team will make all the necessary changes to reduce the transaction price and increase network bandwidth, in which case the price of Ethereum will increase along with its popularity.
