Are people who are sterile, and therefore incapable of #3, no longer alive?

Cells self-replicate. Cells are alive. People are composed of cells. Therefore, people are alive. Sterility is irrelevant.

following the same logic (AFAICT):

People self-replicate. People are alive. Societies are composed of people. Therefore, societies are alive.

(may or may not be a hole in your argument depending on whether you think a society is "alive")

Don’t know why you were downvoted, this is exactly it. Is a book club alive because all its members are alive?
