Hello Tobias,
It seems to me that in the absence of ‘me-view or self-view’ (mana) ,sakkayaditthi (identity-view) would have no ground or basis to get established and nurtured. So even when sakkayaditthi is eliminated at the Sotapanna stage, only the so-to-speak ‘gross’ and even the less gross aspects of the mindset that ‘it is worthwhile and therefore beneficial to acquire things and attributes for oneself’ are eliminated – the much subtler desires for continued existence in the rupa and arupa lokas are not eliminated.
I have not gone deep enough into this before I started typing, but that was my initial reaction. Certainly, there must be more to it.
