I think the point is not "never ever buy a coffee again until the day you die (or retire)". The point is "examine your routine spending and see if you can cut off anything and use it as a source of money for savings". If you did that and consciously prefer saving a little bit less and indulge now and then, these recommendations are not for you, you're already past that stage. A lot of people didn't even get to "consider your spending, make a budget and evaluate your expenses and decide which ones you can do without". They don't even think in terms of considering whether it's worth it or not. I think getting people to think about that is the point of it.
