well, that is more or less the same. So 'a straight worldline' is the 
same as 'unaccelerated movement'.

I would regard it as philosophical question, what is defined from what.


Now I use a simple trick:

Since all inertial observers shall be of equal rights, the inertial 
observer can rightfully declare himself to be at rest.

This is because of the following reasons:

there might be an absolute zero point in the universe. This zero point 
should be at least in respect to itself at rest, hence is inertial be 
definition.

Since the inertial observer is of equal right, he can declare himself to 
be the center of the universe.

Usually we actually do so, thou unconsciously, and declare ourselves to 
be the most important spot in the world.

As we do this, we grant all the others the same right and to be the 
center of the universe, too, even if that universe is different from ours.
