Because some buffer positions would be unreachable otherwise.

No, point is _buffer_ position where insertion happens. It isn't a
screen position.

Yes, but turning the mode on and off is an annoyance.

See above: Emacs attempts to let you reach the buffer text below the
cursor position.

I understand; this just means scroll-lock-mode is not doing what you
want, it's doing something else. Maybe someone will extend it to do
what you want, or maybe there's already a similar mode that does.
