Galaxia’s true purpose before she allied with Chaos was to act as a sort of ‘police force’ for Senshi which is why she has the ability to take their Sailor Crystals. Should a Senshi turn on their planet or otherwise 'go rogue’ Galaxia was supposed to stop them, either by enlisting a Senshi capable of purification, or by removing their Sailor Crystal and taking it to the Star Garden instead of letting it be reborn via the Galaxy Cauldron.
