The problem with 100 years time. Imagine someone like you set up something like this in 1923, and that someone is now dead, and their kids had no interest in keeping it going, infact they had financial problems so sold the site for $50 to someone who let it lapse. You see you need to coordinate people from beyond the grave... a bit like the US Constitution. Hell even countries (in their political form) often don't last 100 years. I am not saying it is impossible, but it is hard, so you need to convince people you are serious. Which might mean, for example working for the internet archive, or a large museum with digital presence for a few years in a senior position, etc. then coming and saying "I am starting this and I know all about keeping stuff around for decades"
