Lately, many Ethereum users have complained that transaction fees are too high when they want to transact with ETH coins, so Vitalik is trying to solve this problem by planning to switch Ethereum to a PoS consensus algorithm which Vitalik thinks can be the right solution to reduce transaction costs, and if after the launch of ETH 2.0 it is as expected by users then of course it will make ETH more attractive to the public, so you don't have to worry about that because ETH is a coin that has a good future.
It would be extraordinary if in the near future ETH was able to solve this high transaction fee problem through the methods you have mentioned because it has been a long time since everyone has been forced to make transactions on the ETH network if there are no other network options for certain tokens or coins.
So I would absolutely be very happy if Vitalik would sort this out in the near future.
