Your point isn't necessarily wrong, I was just highlighting that the story had its own focus and it did it well, so it would be unfair to judge it on something it wasn't trying to be. I think even the unique theme intro, makes you focus on land scamming.
You confused yourself with these expectations, this its own drama, The focus is Takumi. The backstory is that his father was once scammed too, and the plot is that he's unknowingly working his father's scammer. The rest of the story is simply showcasing the sophistication of land scamming.
I bet you expected a tussle with detectives, but the story wanted to focus on land scamming and Takumi's past.

more violence and no comedy.
