A copyright stops the making of copies of a work. It does not affect who owns the existing physical copies. The only way to protect a widget factory in the same manner is a patent. A patent only protect for 17 years, not life+70. So yes, copyright is different.
Now do I think it unreasonable that you should pass the patent on to your heirs, like you can a copyright? I think the length of the term of copyright is incredibly unreasonable right now.
