The HTML spec defines the head property to be readonly: https://html.spec.whatwg.org/#document
That's why $head is marked readonly.

So I guess the question becomes "why does the HTML spec define it this way?"
I couldn't find a conclusive answer to this, it looks like this has been read-only since HTML's early days...
I thought about it but don't really see a technical reason why this is the case. If I had to take a guess I'd say it's for simplicity sake.
