The vast majority of passwords does not need to be easy to memorize because they should be stored in a password manager. In fact, I'd argue that the harder it is to memorize, the stronger the password. Yet they still need to be typed on cell phone keyboards, TVs, or communicated over phone (shared passwords are the best compromise if asymmetric cryptography is not an option), in which case you usually need to spell it out anyway.
