That we know of. In my headcanon, most major cities have at least one super hero, of varying scopes and capacities. Most of them just don't have the advantage of starring in other-dimensional comic books that give us a view into their lives. After all, lets be honest: in terms of larger scheme influence or importance, would Matt Murdoch really warrant notice if not for us being specifically given a look into his smaller scale dramatic life? There's probably a dozen street level vigilantes in different cities who have roughly as dramatic and interesting of lives as Matt, they just don't have Netflix shows.
