When you'd hear it
This pattern appears in general observations, proverbs, and explanatory writing, and is also common in conversation with endings such as 법이지 or 법이죠. It can sound reflective or matter-of-fact rather than casual and spontaneous.
What learners get wrong
법이다 describes a natural pattern or expected outcome, not an obligation; it is different from -아/어야 한다, which means that someone must do something. It often presents a broad generalization rather than a single unavoidable event.
