I, an engineer, am not doing this myself, too. There is a middle ground though: just use a privacy-oriented Android build, like DivestOS. [1]
There are a couple caveats:
1. It is still a bit tricky for a non-technical person to install. Should not be a problem if they know somebody who can help, though. There's been some progress making the process more user friendly recently (e.g. WebUSB-based GrapheneOS installer).
2. There are some papercuts if you don't install Google services on your phone. microG [2] helps with most but some still remain. My main concern with this setup is that I can't use Google Pay this way, but having to bring my card with me every time seems like an acceptable trade off to me.
