But, it's disappointing they don't have actual online coop for people who may want that. 

I'm betting they are doing it this way so that it will work even if your internet is not great.  This seems more passive, so they can probably just let the ghosts lag and it won't effect your game.  If you could directly interreact, then everything has to synch up much better.  If you have ever played the Mario Maker 2 online multiplayer, you know what I am talking about.  Just 1 person with bad internet turns the whole thing into a lag fest.
