I mean...the way you've described it, why not just write a chapter of a book once a week and forward it to the "players" ? You've removed player agency for any significant decision. Players are there to make a story with you. Barring a very specific group that just wants to be told a story for 4 hours a week, this is not what they've signed up for. This is -actually- some of the worst GMing advice I've ever seen.
