If that were the only point then why would anyone inherit from interface in C# and Java? Inheritance not only lets you reuse the code but it also makes sure that an inherited class implements the interface provided by the base class hence the object of inherited can be treated as if it were an object of the base class.

Inheritance helps in the following:
1. Better design of the code
2. Code Re-usability

The 'Better Design' could be exploded further:
1. More manageable interface to set of related classes
2. Supporting run-time polymorphism

1. it allows code reuse from the more generalised class to a specilised one
2. run time polymorphism
3. allows generic reference
