So I don't know where you got "there's nowhere for you to go" from.
Element has open source apps and that's great. It just seems to not have a very strong culture of people self-hosting it. Though one comment did provide me a place to look and I found this and am now more comfortable with it. https://schildi.chat/ Still it would be great to see it have some big instances like GitLab does with Debian, Freedesktop, and others. Then I wouldn't feel I was going it alone if I self-hosted it.
