The aggregate pain and aggregate loss of using cash for transactions in a credit-card dominated world is much larger than the concentrated pain of replacing a credit card once a year. I make significantly more than $30 here and $20 there on rewards - on the order of $500+/year
Sign up for Mint, and quickly scan all of your transactions on a monthly or bi-monthly basis. It's a good idea anyway, so that you can easily account and keep track of how well you're doing at saving.

I have not found this to be the case.

I don't intend to increase the available surface area for attacks by giving my credit information to a third party. Nor do I need this kind of a monthly or bi-monthly hassle.
Eh, I don't view it as a hassle - I view it as a progress check. My savings is important to my future, and checking the budgets, etc. helps keep me on track.
Point taken on the attack surface area, that's definitely something I've always been worried about, and I have no counter.
