Adopting Segwit would start offloading mempool congestion almost instantaneously, How is this not urgent?

FYI, I am running a bitcoin brokering business doing dozens of transactions with beginners every day and had not a single person complaining about the fee costs even when it's the 1$ range. If blockchain.info receive so many support request for transaction fee problems it's because the wallet has constantly been behind in terms of setting the right fee given the network condition. Still to this day BC.info has no reliable way to select Low Normal or High priority.

I've listened to that whole "debate" at anarcopulco and was completely mind blow by your lack of understanding of why zero-confirmation transactions are not and have never been secure. If anything RBF make these transaction more secure by signaling miners that a doublespend really is a double spend when it's not flagged as RBF. You seem to think that because 99.99% of past double spends attempts have not been included by miners mean that the incentive isn't there for a miner to decide to include a transaction with 100$ transaction fee over the standard fee.
