B) keep the blocksize and just increase the fees so its more expensive for everyone to transaction, while not increasing bandwidth for anyone

Segwit is an block size increase. Quit your whining.
my response:
Yes, segwit does do that -- but its a fairly modest increase that is coming pretty late...so we may still get congestion... and on core's terms instead of letting the market decide... And it may not even activate. ...And it greatly increases the complexity of the code. ...And it only helps to the degree to which wallets use it, which is only partial for now.
Like I said - THEIR roadmap. They are giving a tiny bit of on chain scaling, maybe, eventually... while they work on LN.
