They did put Moriarity in his own holo reality. Quite cruel after all. Not sure ehat happened to him, I didn't watch the last season of Picard.

Also, the holodeck: Not only can the ship computers run multiple, basically self-aware General AI characters in parallel, it can also extent space beyond the confines of the decks physical dimensions. Pretty amazing tech, no idea why they don't use it to build the interior of all their ships, after all it also has superior environmental controls.
