A physical observer provides only an *infinitesimal* chart.
As an observer, I define x,y,z,t axes going out from me (the origin),
but I can't describe how the axes will curve as they
leave me.
So, I can't define a chart large enough to contain two distinct points
and any geodesic linking them -- which is what you wanted here.
