That supposedly fixed true north is not really fixed, for the earth's axis precesses over a 26.000 year cycle, not to mention that the whole earth moves.
Good point.
So, iff a "fixed-point" is required, in order to properly answer the question "where were you born", you'd be forced to calculate where exactly the planet earth was, relative to its orbit around the center of the super-massive-black-hole at the center of the milky-way-galaxy at the time of your birth (and additionally the movement of the milky-way-galaxy as a whole, relative to its current position).
In other words, you were born very very very far away in a (most likely) probably empty region of space that is going to be extremely difficult to pin-point (and you'd probably need to devise some sort of novel universal-grid-division of space-time itself (UGDOSTI) in order to reference the precise location of that "fixed-point").
And even this "fixed-point" would be more of a "smudge" or "streak" through several discrete UGDOSTI points because the planet earth didn't simply stop moving between the time you started being born and the time you were actually fully extricated.
