I think you have a valid point, but then the same could be argued for Wikipedia vs. Encyclopedia Britannica or pretty much anything else that's successfully crowdsourced online. Of course the artist would have to curate at the end and only pick parts he loves and fits his vision for the song, I just know for a fact that there isn't an objectively "right" part for any song, so an amateur kid in a remote country might actually create a bass line that fits the artist's vision for a given song better than what a professional session player has come up with on that specific day the artist had to work with him. It won't sound as good, obviously, but then the artist can re-record it properly. And the positive side effect is, of course, a lot of fan base engagement.
