Using your existing node is great but you explicitly stated that it isn’t set up to do that. I’m just pointing out that using cashu to make the transaction doesn’t have to have anything to do with your funds that you aren’t already planning on sending to people you don’t know.

The risk profile of using cashu to make this particular transaction is low since you wouldn’t be holding the funds there.

Not wanting to involve a third party in the transaction is a separate reason and totally valid
