I like paper money. I like to feel the buying power in my hands :p Bitcoin makes me feel like a robot. I am not saying paper money is better tho.
As what other business policy, "credit is good but we need cash". Sometimes people prefer to use paper money than Bitcoin for some reason. Paper money is easy to use, you don't need to convert or exchange in your own currency just to buy simple stuff. So I agree with you, paper money is much better that using Bitcoin in buying such things. And also paper money is controlled by our government so it is secured whatever happens in the future.
