Well, "big blockers" for me are the guys that want to stay on-chain even with microtransactions and want 8 MB or even larger blocks now - and so run Bitcoin Unlimited. Segwit means "bigger blocks than now", but not really big blocks (<4 MB).
I consider everything above 1 MB as 'big blocks'. This is due to the narrative of the 'small blockists' (to call them that) who want 1 MB or even less right now (see luke-jr BIP).
Yes, that would be an ideal solution. However I am not aware of an initiative that actually has the goal to convince the miners that are blocking Segwit from that kind of solution. If there is any and there are news about it, I would be glad with you or anybody else providing me a link to it ...
Well, you can't really convince the miners when there isn't a HF proposal that properly does this post-segwit. The only BIP that increases the block size sometime and builds on-top of Segwit is luke-jr's. However, that one does't see any growth until a few years into the future.
Price is tracking BU's odds to win. Bitcoin economic majority = market wants BU and on-chain scaling now.
Bullshit and you know it. The market gives zero fucks about this trashware called BU.
