3. I will not remember most of my life moments. So they are dead ends in my life story. If we agree with your definition of identity it would mean that I die thousand times a day. Not pleasant and not productive model.

I'm not sure if you've made this mistake or not, but I know I have in the past. Just because something is unimaginably horrible doesn't mean it isn't also true.

It's possible that we are all dying every Plank time, and that our CEV's would judge this as an existential holocaust. I think that's unlikely, but possible.
