Thanks for clearing this up, that makes sense now!
Now I note that a single Starlink ground station is generally within
sight of and set up to handle multiple satellite links (all known images
show 6 or more radomes). As each bird has ~20 Gb/s capacity, I guess
we'll probably be talking 100G circuits here (where they can get them).
And the move to dark fibre is a logical step then.
