It seems reasonable to me that when something is characterized by
weight per unit length* a piece of zero length has zero weight.

The concept of zero itself as part of the real number system
is mind bending enough for it to be a fairly recent invention
in terms of human history. IIRC, Zeno's paradox wasn't
mathematically refuted well until after the time of Newton
when calculus and set theory were put on more formal ground.

In terms of reality, I'd also ask how would you measure zero
length, given quantum uncertainty, and zero weight/mass given
that even a vacuum is though to have non-zero energy potential.
