Thinking of Canceling My CSP—Can Someone Give Me a Reason Not To?

I've realized the CSP isn't doing much for me. I don't even book a hotel once a year, and now I can't use it to churn that $100 anymore. For everyday spending I just use the UAR—simple and hassle-free. Can't help it, I'm lazy. I signed up for DoorDash before but never use it, so I just deleted the app. Honestly, I can't think of a single reason to keep this card.
