They sort of addressed this in Deep Space 9 when Quark tries to use Kira for a high paying customer. So there’s a little story line on preventing using unwilling characters in this way.
Totally agree that there should have been a mention of giving consent earlier on. The Jordi/Dr Leah Brahms storyline does touch on how there was an abuse. Perhaps Starfleet later on added the restrictions that are seen in Deep Space 9.
