You aren't going to keep coming back to a chuuba's stream because you like the avatar and only the avatar unless you're really shallow. Their personality is what is going keep bringing you back. A real test of this is to watch some of a chuuba's stream where the Live2D is broken or is just a png, or maybe not even that and it's just the voice.
Even for chuubas who are obviously playing a character like Pekora, finding someone to replace just wouldn't work. They could say peko as many times as they want, but the the nuisances and personal touches of the person behind the camera would be gone.
