About not being able to say if I'm better off having been born, I don't know/remember what it was like before being born or being dead, it might be amazing, I don't know, so I can't compare. Doesn't mean I want to be dead right now. I also never said there's no point in being alive.
Why does life need any "terminal values" at all to be meaningful? Do you think there needs to be an absolute truth to it? What if someone disagrees?
