What it means
うものなら follows the volitional form of a verb and presents an imagined action as a serious possibility, usually implying that the action would lead to a highly undesirable or severe consequence. It is commonly used in warnings, threats, and emphatic hypothetical statements. The construction often carries the nuance of “if someone were to dare to do something” or “should someone do something,” rather than a neutral condition.
Usage note
うものなら is much stronger and more literary or emphatic than an ordinary conditional such as たら or なら. The consequence is normally negative, and the construction is generally used in formal writing, serious speech, or dramatic statements.
