Just to be contrary: perhaps the OP has a point if not well expressed.
If instead of "lock out the controls" Picard had said "lock out the controls and then separate the ship", he'd have a working, presumably Borg-free saucer to use to try to rid the engineering section of the Borg. They could do the combat sequences by transporter (and only the saucer would have functioning transporters) and the dish sequence would work as well.
In fact, they could use the transporters as a weapon, beaming off Borg drones and technology into space.
However, you wouldn't have the relentless Borg taking over the Enterprise deck-by-deck directly threatening our heroes. The final "lets blow up the Enterprise" would be the saucer destroying the engineering section... no need to go to earth, although they'd be fairly uselessly stuck in orbit. Perhaps they'd have to leave the saucer to escape the antimatter blast... they might remember what happened in the prior movie.
Picard could beam over to get Data before the blast, i guess.
I don't think the idea occurred to the writers and they had separated the saucer just movie-previously, in Generations.
