Maybe the relative ease and affluence of our lives has diminished our willpower to deny ourselves anything, and exercising our willpower will strengthen it. In other words, maybe the 'limited' part is artificial and can be changed. And maybe strengthening our willpower would benefit us beyond just denying ourselves arbitrary comforts. Such as, willpower to pursue adding to or honing skills, maybe even ones that don't reap immediate material benefit. So, cutting out lattes may make you better able to improve as an entrepreneur, or programmer, or whatever.
