That makes no sense. By that logic we shouldn't spend any effort on education, we shouldn't have children or any long term plans whatsoever. I think I already made that point in a comment long ago where someone said you can't take things with you if you die. Taken on an extreme. Imagine if a person dies and he could actually take anything he desired with him. He'd certainly bring his family and his house and the planet he lived on with him. The end result would be 8 billion dead humans who no longer have a planet and were left behind. Is that really the type of world you want? People committing vandalism and self destructive behavior because they have nothing to lose?
