I was responding to a specific point to which your response seems irrelevant.
If my kids, or their kids, or their kids, etc. ever wanted me to die in order to "bestow" them with something...well, too bad. I wish my grandparents, and their parents, etc. were alive today.
Space on earth is finite. And even if add more hypotheticals like us becoming an interstellar species (actually I'd wager that's less unlikely than overcoming aging), in absence of aging exponential breeding would eventually outpace even the fastest space frontier colonization imaginable.
