For me, this is quick funzies/neat and other project and business usecases, is why i implemented this on my stuff, and I agree it's important to mention to the users the public-ness of this and its potential implications, however, this is also a 'step 1' of a two-stop goal, for me at least, where the other step is 'nostr silent payments (nsp)', so there'd be an option to send to a random address controlled by the receiver.
