Advanced privacy - perhaps a bit too paranoid?

Using /e/OS Applications

With all gates closed the phone, i.e. browser appears sluggish and almost useless.
Can anyone tell me which ‘gate’, (ip, position or trackers) is most critical to keep closed?

I am happy with all adverts blocked. How dangerous is it to not fake the ip-addresses?

I’m only using the tracker blocking functionality. I find the “plausible” location to be not at all plausible (and several apps on my phone agree), and my IP address is already hidden by ProtonVPN.
I love the idea but right now its a bit of a headache.
