That may be true in physical observations, but doesn't make "point
of application" a vector property. If you had it as property, you
could never say that in a force field the force was equal at two

This is also contradicted by the fact that complex numbers are used
to represent vectors. A complex number only has a "direction" (in a
plane) and "length". Not more.

To which points "apply" velocity vectors, unit vectors, or axial
vectors (like angular velocity)?
