It sucks that we need such an extensive amount of work put in to make devices private
The issue is that, short of the extremes suggested in places like privacyguides, you’re not really making the device private. You could argue that you’re making it more private, but the counter-argument is that you’re still leaking so much data that you haven’t significantly improved your situation.
Doing something probably is better than doing nothing, but it’s not going to satisfy those who seek actual privacy. If you’ve got a particular leak that you’re worried about it’s definitely worth looking to address it though.
Whilst you’re right about privacy not being binary and the need to create your own threat model, the problem is that all the different parties that collect your data trade it, so if you leave one avenue open, the others that you tried to block are likely to get your data anyway. Whether this fits your personal threat model is probably an individual decision.
