And who shows up to these anime clubs? Fans of anime, or people specifically selected by their friends who are already also fans of anime (and thus tend to be in similar demographics), and very rarely random people who are not scared off by the esoteric and by the genre (again, primarily young people and somewhat slanted towards young males).

Also, respectable Anime Clubs point you to Crunchyroll nowadays, because that's more respectable and entirely less legally-murky ;)

But yes, it's not that hard nowadays, mostly trivial inconveniences. Most anime fans that are relevant here would have started watching anime years ago, though. The first five websites I used to find and watch anime do not exist anymore.
