Segwit is DEAD!
You are right, with current settings about consensus, SegWit has (unfortunately?) no chance to come to life.
The system will continue to work with the current rules fine. There is currently no show stopper bug that makes changes mandatory.
I don't agree. When 40MB mempool is usual, when people come here each other day asking why their transaction (made with perfectly valid wallets) are not processed, then it's not normal.
I feel like the devs should have somehow enforced this (with the risk of ETH fiasco, I know).
No. If you don't like what some miners are doing, don't relay their new blocks. It's up to you, not the developers!
So only the miners and the nodes have the power to do anything.
And the rest, the ones paying for the service, (me included) can just go to h***, right?
No. There has to be another way.
