Morgana does pester you to go to bed in the original Persona 5 on days where plot-important events occur. You seem to be acting like a willfully-ignorant fool who never played Persona 5 in the first place.
I looked into it, and I still don't understand how "You must be tired after today, you should go to sleep" is pestering, especially considering the tone Morgana delivers it in, and how the protagonist just stops on his own will, and at times even nods at his advice. You seem to be acting like Morgana is being openly rude and forceful with him, and that the protagonist is consciously frustrated at these actions.
He may not be actually being rude and forceful, but it does showcase a scrappy mechanic that should have never been in the game in the first place (Morgana not letting you do anything at night on days where plot-important events take place). I will admit though, I am at least trying to be polite here because I don't want to be blocked on this site or across the network. I could have invoked Jim Sterling and used his Skeleton Warriors gag where the intro to Skeleton Warriors interrupts any usage of the C-word, but that would have gotten me blocked on this site at the very least.
Whether it's a strange mechanic or not, I don't understand why we should pretend that Morgana consciously limits the protagonist's free will? In the end, he speaks for the protagonist's feelings, who chooses to stay at night. Though it can lead to misinterpretation, the disconnect is between the player and the protagonist, not the protagonist and Morgana.
The thing is, the protagonist is the player. As a silent protagonist, he is entirely left up to the player's decisions, and, as such, Morgana is actually forcibly limiting the player's actions. While, from a lore standpoint, ignoring the fact that it's a video game, you are correct, but Persona 5 is a video game. As a result, the player is the protagonist, and the player is forcibly limited.
For the sake of the argument, let's say that the protagonist doesn't have a pre-set personality, and that it's all up to the player's interpretation.
The idea that "Morgana pesters and forces you to go to sleep" is still just somebody's interpretation.
If the protagonist doesn't have a pre-set personality, how can you say what Morgana does definitively bugs him? Wouldn't it be better to avoid implanting ideas that only exist within certain players's heads?
In general, most people prefer to be allowed to play the game. If you prefer to be limited, then good for you. However, a majority of people prefer to be allowed to take additional actions. As a result, the page looks the way it does.
As a point of curiosity, why are you so vehement about this? It seems like an odd topic to white knight.
