How about these? Use case: A person sends money to their friend using a memorable identifier instead of a complex account number or URL. The memorable identifier is translated to a destination account for the payment. The friend should be able to easily communicate the identifier via voice, SMS or other short message and the person should be able to easily remember it. Use case: A person needs to pay a (large) merchant for a purchase. They should be able to easily check that the destination is legitimate and, for example, not the address of a spammer (e.g. payments@amazon.com is preferable to a numerical account number and simply "Amazon" is preferable to a longer identifier because some users may be fooled by something akin to "amazon-payments@banksrus.com"). Use case: A charitable organization or cause posts a donation address on a print advertisement. The address should be as memorable as a social media username so prospective donors need not use QR codes or type full URLs, potentially on a phone, to send a quick donation. The point about not wanting an address to be discoverable is a good one but I can't think of a way to write it as a use case. I'd also include that people want to be able to transact without any of the details of those transactions being made public beyond the sender, receiver, and any relevant financial intermediaries.
