Given how the writer was having a hard time constructing sentences and getting across his thoughts, I don't expect for him to come up with this idea. I think it's mostly he didn't know who Taskmaster really is except for his mimic ability.It is simple - Taskmaster in the comics trains troops and is a merc for hire. He happens to have a great skill set in mimicing people's movements. How cool is that? So clearly you have him train the Black Widows. I mean, doesn't take a genius to put that together. The Nat family gets together to take it down while other Widow's are trying to kill them. Taskmaster is the adversary that takes all of them in order to take him down. They wanted Dreykov Weinstein to be manipulating all women, that is pretty obvious. Surprised they didn't show Dreykov hanging Epstein in his cell. Still surprised they used Bill Clinton meeting with him.
