I totally agree. The perception that, say, credit cards are fast and free is completely wrong, and based on the comfortably ignorant idea that things that only impact other people don't really exist.
If there's one useful thing to take from it, it's that I think it does usefully highlight just how critical that perception is for adoption -- specifically, how thoroughly it dominates technical concerns like throughput and latency. Perhaps if shop owners were prepared to eat the bitcoin transaction fee the same way they eat the credit card fee, bitcoin might have a resurgence as a cash alternative. There would still be the transaction speed issue -- I think it would require a third party to step in to provide merchants with guarantees (in exchange for a fee), so that the merchant wouldn't have to wait for the transaction to go through. But that's not a tech problem -- it's the same problem that credit cards already have, and have already solved.
