Copyright does not protect work ("sweat of the brow"), it only protects expression and creativity. Thus, whenever there is only one right expression or even a bare handful in any given context, copyright does not apply to that particular choice. By analogy, arranging words in some semi-arbitrary order can be an expressive choice, whereas using what's effectively a fixed phrase is not, even though the two might look similar and involve a comparable amount of "work".

The intention of copyright is to protect useful work.

The detail of how to do that in fair way that doesn't block other people is complex[1] - you can never cover all possibilities in a written law - that's why you have people interpreting them and making judgements. All I'm saying is the guiding light in that interpretation is copyright is there to protect the justifiable work of people in a fair way.

Somebody taking those law notes and trivially copying them to directly compete is clearly not 'fair use'.

If those notes could have been created mechanically directly from the original source - why didn't the copier do that - rather than use the competitors work?

That's actually a very good question. In practice, I do absolutely agree that the notes involve plenty of originality and creativity.

Not sure where you got that quote from, but I'd say the work aspect is implicit in the "promote the progress" - ie progress requires that people are able to get paid in their work to progress science or the useful arts.

If the progress was trivial and required no work then it wouldn't need protection or promotion.

And sure it's phrased that way to get the balance between fair use and protection - but if there was no need of protection then copyright wouldn't need to exist - as free reuse is the default.
