Budgeting with the data trail of a card is significantly easier if you have a lot of transactions. It's also generally cheaper due to cashback and other incentives. Other than that I've always found the idea that cash is "inconvenient" a bit of a child-like argument.

We improve our life with technology all the time. Electric lights, refrigerator, AC, washing machine, dishwasher, electric toothbrush... Nothing "child-like" in trying to make your life better, even in small ways.

It's a fake argument, it's not that big a deal, you just didn't care enough about reading books.
