I don't know enough to agree that it's pointless, but I'd agree that when I looked at it I saw a lot of abstraction of already simple stuff (like the examples the post gives) and decided that for what I was doing it would be faster and easier to understand to just write my own python script. Though I can picture for very inexperienced developers the abstractions may be helpful short term?
I had a similar experience; looked into using it for something, and felt that it would be easier to recreate the things I would use langchain for in Jinja2, than it would be to reshape my code to the interface that langchain wanted.
