The argument is flawed. You defend. "if it has a cost and lasts through evolutionary time, it is beneficial." But to conclude your conclusion, you must also show that: - emitting noise has cost (fairly believable) - and that something listening to it is the only way to make it beneficial, which is far from obvious. (Could just be a way to dissipate energy, or to send signal within the plant, or to get rid of some chemicals, or many other beneficial things that doesn't involve something listening)
