Because the term "weight" refers to mass in most contexts, and always
has. A balance scale measures mass. The contexts in which it does
not (e.g. when talking about "weight transfer" during braking or
acceleration) are the unusual ones. In the case of one's body weight,
it's mass being referred to.

The Physics 101 claim that "weight" refers only to force just isn't
true, except perhaps Physics 101 textbook problems.
