Budgeting using a tool like YNAB has allowed me to manage monthly funds more effectively, pay off debts faster, and save up more quickly for the things I want to buy.

That's good for you, but it sounds like you are spending way more time managing finances online, than I do offline ;) I have an average weekly budget that I keep track of in my head, and that's it. That's also the reason why I prefer paying in cash. Easier to keep track of the outgoing money.
It definitely is not. How is keeping track of random cash purchases in your head easier than a computer doing it for you automatically and instantly?
