You don't need to. Just use apps that do not need Google Play Services. F-Droid helps out with that. I don't miss anything since almost all services I need to use have very good mobile websites. I'm glad I'm not unknowingly sharing a bunch of my data with them.
If I could survive with just apps that don't need Google Play Services I would have seriously considered staying on Windows Phone despite security support ending in November.
We've lost the App War. I need multiple Apps that "need" Location Services and Push Notifications just to get what used to be hole punches or stamps on business cards for buy 10 get 1 free sandwiches in 2019.
Options like LineageOS and going without Google Play Services might as well be a "dumb phone" in current culture. It's an hilarious joke. Google realized all the real control in Android was in controlling Google Play Services, and as soon as that got locked down people should have been worried. Google wouldn't have had as much power to "kill" Windows Phone that they had if apps didn't matter.
(Fwiw, I went back to Apple as that unfortunately seemed the only sane choice to have Apps and some semblance of maybe Privacy.)
