Thats a fair question! I ask myself this daily as well..
To answer "why am I grinding" or "what's the point?" Because, what's the point to any game? RPG, First Person Shooters, etc. We play and finish those, but why? We get nothing out of it overall. So just have to step back and just enjoy the games for what they are. I treat MLB just like that, a game I'm just trying to beat.
I just enjoy baseball, and I'm 100% in on how they doing content this year. I made a google doc and make sure when I'm playing I'm playing for a reason. Clearly this content is super easy, nothing to difficult, and once I'm done with things I move in and play Online. Even if Events or Ranked grind is done. Just to play, gameplay to me is enjoyable. I'm not elite, very average, but I have fun and compete and hold my own.
Overall goal? Just to keep up and stay current with the content, collections etc. With that said, rinse and repeat the same things over and over and over.. But what else can they do? Maybe dump Extreme Seasons/Moments etc on us? I'm for that to add a challenge..
But again goes back to why? Because we can just ask ourselves that for every dang game we play.
