I'm of a similar mind. I sort of resented the tone (that might have been perceived) in the article that not using a credit card is some kind of marker of a financial dummy or irrational paranoid.
I pay cash for everything. I have a stable checking account, savings account, and several investment accounts that has my money working for me and growing. I'm completely aware of what the credit cards offer and I don't think it's valuable to me or my goals.
The only credit I want in my future is potentially a home and if I can make that happen in cash, I will, or at the very least a down payment that keeps the credit line realistic to pay off before I'm senile.
