You seem to overlook that the "expansion" is very likely just

No, it points in the direction of higher entropy.
Sure, but the physics is such that entropy must increase in the
direction of expansion - the two are linked (that's what I meant by
"nomologically necessary").
I disagree. There is no necessary connection between the expansion and
the increase in entropy. The total possible entropy might increase with
expansion, but if we are always a long way below the total possible for
a given volume, the entropy could increase whether the universe were
actually expanding or contracting. Anything else and you are necessarily
committed to a reversal of the arrow of time if the universe begins to
re-contract at some point.
