Apple Music on Mac missing Listen Now and Browse (solution found in strange place)

This was a weird problem. I just started my Apple Music trial. It works fine on my iPad, but on both the Macs I use, I see:

Library
 Recently Added
 Artists
 Albums
 Songs
Devices
 (my iPhone, but not my iPad (other problem, I guess...)
Playlists
 All Palylsts
 GarageBand

Missing is:

Apple Music
 Listen Now
 Browse

I searched the forums, and the question has been asked several times, but the solutions go in several other directions, and there is little follow-up or expansion of the topic, and this particular solution was not suggested in the several discussions I read.

The solution for me was to launch Music and then click Music - Preferences - Restrictions. There I had

iTunes Store

disabled.

I did this years ago because iTunes was an ongoing source of problems, and I didn't want to use it. I don't even remember all the problems I was having, but I imagine a lot of Mac users did the same as me. Now I still don't care to use iTunes, but I'd like to try Apple Music. IT DOES NOT SAY ANYWHERE IN THE SETUP FOR APPLE MUSIC THAT THE TWO ARE LINKED, so when I originally checked on this missing Listen Now and Browse problem, in these very settings, I did not re-enable iTunes Store.

So, I took and chance and unclicked

 iTunes Store

and suddenly

 Music Profiles
 Apple Music 

appeared in iTunes Store's place. And now Apple Music is finally working for me on my Mac.

Is this an unintentional oversight that has persisted because none of the developers at Apple had iTunes Stores disabled? Re-enabling iTunes Store was not an obvious or intuitive solution to this problem.
