Answer
It keeps raw fields from being mutated arbitrarily and lets the class enforce simple business rules.
In early object models, encapsulation gives each class a clear boundary around its state. A Product can reject invalid prices or hide how a value is stored instead of letting every caller edit fields directly. That keeps the model easier to reason about before the design becomes more advanced.
