It's called copyright as things change when works are easy and cheap to copy.

Replicating work of an electrician or builder is very similar effort to their original work.

Making a copy of a novel or software program or art today is practically free.

In case of work for hire, things pretty much work the same way already — company owns the copyright, except in some jurisdictions where actual humans keep "moral rights" and reserve the right to renegotiate the fee if the work produces disproportionate earnings (one cannot even transfer these rights away).

But if you did the work out of pocket, how should it work? Any recipient could trivially and cheaply produce a copy and distribute it. If you do not get any exclusivity at all, others would profit a lot more and you'd get nothing at all.

So in general, there are multiple things:

* exclusivity lasts too long (I understand some motivation like supporting your children off it, especially if work only became profitable late in your life or in death, but you could have different mechanisms too — akin to moral rights, exclusivity could run from the moment it turns a significant profit like an average annual salary, and for a fixed, much shorter period after)

* types of works which are utilitarian (like software tools) should have entirely different treatment

* it should ensure both transferability and perpetuity of use (no licensing bullshit and your games/music are gone because our service does not offer them anymore)
