flimsiness
Lack of durability
Flimsiness is the quality of being flimsy—thin, weak, or easily damaged.
A structure built with flimsiness won't last: The flimsiness of the shed was obvious when the first storm hit.
The word extends to ideas and arguments that lack substance: The flimsiness of his excuse fooled no one.
