I don't know what you consider the meaning of life and your ultimate goal, but in the real world, the goal isn't to mindlessly consume in a hedonistic way, but to raise and nurture your offspring. The only reason someone shouldn't have and raise children is if that person either has a major genetic defect that would negatively impact his or her children, which is an understandable and unfortunate reality, or otherwise that person is just a colossal jackass who would inevitably kill or otherwise neglect a child, a perpetual adolescent, and that lifestyle is selfish.
