The probable crazy switch for Dany in the books is fAegon. She's all busy in Mereen, meanwhile fAegon is out there taking Westeros from Cersei and fixing stuff.

When she finally gets her shit together and goes to Westeros along with the Iron Fleet and Mr. Cthullu, the liberator card doesn't work because no one needs to be liberated so she goes nuts. All the pride, violence and idolatry in her arc makes sense.

In the show she was just replacing Cersei. No one likes Cersei, she'd still be a liberator. We'd need Jon unseating Cersei while trying to unite Westeros before Dany arrived for it to make sense. All we got as a trigger was a scene where she was sad because the members of the patriarchal society she just arrived in with three giant fire lizards don't want to drink with her.
