For this particular operation, land-based aircraft have proved sufficient. Yes, if there'd been a UK carrier with an air group of FA2s and a few GR9s and if it had happened to be in the right place at the right time, it might have helped.....
So the carrier / Harrier argument is irrelevant for this particular scenario.
But next time, there might not be a suitable land base close enough. Would that be sufficient reason to resurrect the Harrier force? I would say no - unless that force were to include the FA2. Otherwise it would probably be an expensive luxury which simply couldn't be justified.
Pity though.
