Ever been to Las Vegas? Of course not, I should know better than to ask. Ok, well, in Vegas or Atlantic City or Monaco or any other gambling casino town they use chips, not cash. In some places they're replacing chips with a card. Why? Because when you don't see cash, you don't think about what you're spending. It's just plastic.
If you take cash out of the bank and try to live on it, you'll quickly see how much it "hurts" when you're buying stuff.
Some mentioned that cash is hard to track. You're too young to understand why some paranoia about that is warranted.
Finally, what do you do in an emergency? When a hurricane hits and there is no power, your credit card is useless. You should always have some cash stashed away for an emergency.
