Your analogy breaks down at "because of a grudge or whatever." The reason the miners are pissed is because ethereum is proposing to stop paying them. So what if the bouncers shut down the event because management told them they're not getting paid? Sounds pretty reasonable to me.
That's not true, they can still join a staking pool if they want to continue being "paid", so really it's just the way they're being paid that's changing.
Not to find a solution, it was already found. The roadmap plan was always to switch to PoS, the miners and PoW were always temporary until it was developed / ready. Now the beacon chain (core of PoS) is live, with around $6 billion staked. Some of the miners (not all of them by far) are complaining they're no longer going to be needed, going so far as to make a show of "force". Others (like f2pool) have calmly been preparing with rest of Ethereum community, and are transitioning to staking themselves.
