Yeah, it turns out that in very specific and controlled situations, using a fan to make downforce is great. It's also a very obvious thing to do in those situations and doesn't do much for you otherwise.
Imagine a normal car having to carry around the added weight of fans, COPVs, and the plumbing to make it work. And only being able to use those only if the track is clean and there are no other cars nearby.
