In my opinion, the real antagonist in Daisy Jones and the Six is the band members' addictions. Daisy is addicted to all kinds of drugs and it often leaves her vulnerable to being hurt, and Billy Dunne, the leader of the band, is sober but constantly tempted to start using drugs and alcohol again. There is no one person who's the antagonist, instead, it's their temptations and addictions that are harming them.
