I am all in on the privacy. I do the things you listed, plus more.
F convenience, convenience is how people stay enslaved to their big tech overlords.
It was difficult at first but over time I got used to the inconvenience. This made me realize that most people are weak and just follow the path of least resistance, even though it is harmful for them.
Given a choice between a world with "cheap" and accessible entertainment (Netflix, doomscrolling platforms, sports games, p0rn) but a very draconian government, or a world with a near-perfect government and much freedom but no easy entertainment + you have to actually work hard for such things, I think most people today will choose the former.

so yes:
self-hosting, cash, encrypted everything, no big tech (except when acquaintances use it), no social media, no scrolling, no cell networks (except for emergency), no closed source software etc.
