It sounds lame, but it in no way reflects reality, so i don't understand what your point is. Under the current system, the recently deceased authors book would earn royalties for his estate for 75 years. Grand children he's never met will benefit financially from his work. We grant them a monopoly, and get no social benefit. This is a perversion of the intent of copyright, which was to promote more creative work.

Simple inheritance is categorically different. Your inheriting money from your family has no negative impact on others. But if you inherit an intellectual monopoly, it is taking something away from the public good for no benefit. That may be acceptable for a reasonably limited term. But how anyone can imagine a copyright term that extends across multiple generations is reasonable is beyond me.
