Looks like i misunderstood, however what if all miners use non-SegWit nodes, others use SegWit nodes and there's transaction from/to Bech32 address? AFAIK this will make such transaction never confirmed/included by miners.
If all of the miners decided to run non-Segwit nodes, I'm sure that would hurt the market value of BTC, and hurt their bottom line. I am sure there will eventually be at least one pool that will relent and go back to verifying segwit transactions. Or someone in this space will create a new pool that does run a segwit node. Since that pool would be paying out slightly more due to the transaction fees, many miners would switch to that pool. Other pools would probably be swayed to abandon their little boycott and start mining segwit tx again.
Interesting theory, but there are few things that i don't understand/agree,
1. Why would price of BTC hurt? I don't see anyone would dump Bitcoin (whether it's from pro-SegWit/anti-SegWit), unless they don't care about price of BTC/losses
I would think the fact that all of the miners are colluding to boycott segwit transactions would be considered bad news to traders.
2. I don't see correlation between SegWit transaction and higher fee transaction since SegWit have lower transaction size (which leads to less fees), unless SegWit supporters intentionally do that to attract people who actually don't care about the boycott OR block is far from full and mempool only contains SegWit transaction.
A pool verifying segwit transactions in their blocks would include both non-segwit and segwit transactions. The block would have more transaction and the total fee would be a little better than a pool that verifies non-segwit transactions only.
If A is the total fee of all of the non-segwit transactions and B is the total fee of the segwit transactions, then A+B>A.
