Here's why:
* "Natural resting place" is not a clearly defined concept. For example, is a book on a table in its natural resting place? What about a rock on a mountainside? It depends on what forces are acting on the object.
* Objects can move by themselves due to various forces. Even if an object is in a seemingly stable position, forces like wind, water currents, gravity, or even internal pressure can cause it to move. Think of a leaf blowing in the wind, a river eroding a rock, or a volcano erupting.
* "Move by itself" can be interpreted in different ways. An object moving due to external forces is still moving "by itself" in a sense, as it's not actively being moved by a person or machine. However, if you're talking about objects with self-propulsion like animals or machines, then it's a different story.
Therefore, it's more accurate to say that an object in a stable state might not move *easily* by itself, but it's not guaranteed to remain motionless forever. There are always forces at play in the universe, and it's unlikely for an object to be completely unaffected by them.
