If problems have seemed to be solved with curved geometry that could not be solved with straight geometry, it is only because those problems were too subtle for mathematicians of the time. [etc.]

Euclidean geometry is based on an assumption, which is illogic and not 
supported by nature.

To have three rectilinear axes requires straight lines and right angles.

But nature does not 'like' right angles. 90° is just one example of an 
angle and no phenomenon in nature uses this particular number.

Also streight lines or circles are not found in nature very often.

Those are human artifacts and not a feature of the world around us.

So: what would be a better and more natural way to describe positions???

Well, first you need an 'anchor' point and known directions.

On Earth we use a clock, a compass and an altimeter to define a position.

This includes two angles, one distance (hight) and time.

These angles are spherical angles, which are based on the planet we live 
on and where we like to define positions.

(The clock we need to find the longitude of our position.)
