>we consider a point between the two endpoints (i.e. one point on the straight-line), which has no length and no width, is dimensionless, and therefore it doesn't fill any space on the straight-line but cuts the line into two lines which can be taken separately without any trouble.

The point you are not getting, that you refuse to get, is that that point belongs either to one, or both of those two lines. If both (which is almost certainly how Euclid would see it) then those two lines are not disjoint.

Not disjoint - they overlap at a single point.

Cheers,
