Besides what others have said basically asking “what is it that you’re trying to protect (from)?” I would say the main questions in terms of usage are, are you on a degoogled Android phone and are you using Linux on your Desktop yet?

Yea sure VPNs are nice but I personally often feel like I don’t want to have to hide behind someone else’s IP-Address just to add a layer of obfuscation to the data-collectors. If your browser is clean and working for you there is no need for a VPN (unless you need it for the sake of coming from a different geolocation). If your Operating System isn’t Open Source it can be assumed to be tracking you with or without a VPN.

There are definitely downsides (especially in terms of convenience) to using Android without Google on it. If those inconveniences are too much for you (as you are alluding to in your described hassles) then it’s probably just a question of which desire is stronger. That for certain privacy or that for ease of use.
