I don't look at Patreons that often, but if I think about the dozen or so that I have (maybe half of authors) none of them have had pictures of themselves on it, or audio recordings of themselves.
So, I mean, it takes being somewhat charismatic in writing, but of the other properties you list... I don't seem them as important at all. Moreover, being charismatic in writing seems to be practically a requirement for being a good author.
Nor is it like the previous model did not have biases, you needed to be good at selling yourself to publishing houses and the like instead of to readers directly, but you still needed to be good at selling yourself.
