I'll try a simple analogy: imagine that your goal is to consume as much corn as possible. (A silly goal for many reasons, but that's a different discussion.) You have all of the corn that you've grown to eat, and then there's the seed corn you would need to plant in order to eat more corn in the future. If you decide to eat the seed corn as well, you will eat more corn in the immediate future, and then much less corn after that. Clearly limits to consumption are sometimes necessary in order to maximize consumption over the long term, even if you grant the premise that maximizing consumption is desirable.
