Bill, you are getting off into philosophy again. I'm not much of a philosopher, so I don't worry about things you seem to be worrying about. As far as I am concerned infinity basically means that there is no beginning and no end. Of course that kind of disagrees with my reference above to the infinity of positive integers starting at zero, but when it comes to philosophy I just can't get all excited about that sort of thing.
Now I do feel kind of uneasy about the idea that the universe has no beginning and no end. Intuitively I expect everything to have a beginning and an end. At the same time I have a problem with what there was before the universe came into being. However, that doesn't affect my daily life and all of physics still works just fine, so I don't expect to wake up in the morning and find out the universe has disappeared. Therefore I don't worry about it.
