That anonymous account knows where you live, who you talk to, where you go, what you read online, ...

Linking it to your legal identity isn't hard. Data show that just two ZIP Codes (in the US) can indentify an individual with 95% accuracy: your home and workplace.

Makes me want to rightgrade to an uncontracted dumbphone and a custom-ROMed tablet. Not linked to any Google accounts.

Yeah, but that's mostly useful to law enforcement, if they were interested, and for that the mere fact of a cell phone is enough to get everything you mentioned. What Google gets of value out of this account is greatly reduced, especially as I've been buying the ad-free version of the apps. (While in theory Google could get everything you say, I believe that in practice they actually do not, say, forward all of your "Reddit is Fun" actions up to the Great Google Motherserver.)

And no, I did not say eliminated. Just greatly reduced. (Again, the moreso after shuttering Reader, although I must say that while you could learn a lot about me from my blog reading list, its utility for selling me stuff was pretty low.)

De-anonymization has been studied and applied by various parties, and I'm personally aware of at least one non-LEO application. I don't know that Google does or doesn't do this, though it wouldn't surprise me at all if marketing/advertising and/or other "personalization" services did. It would annoy me intensely to find that they were.

For that the mere fact of a cell phone is enough to get everything you mentioned.

A dumb phone can only report coarse location information, SMS messaging, and calls data. Frequently expiring SIMs would limit the useful duration of much of that information, though you'd need something like a self-hosted Google Voice forwarding service to be able to use the phone usefully while maintaining reasonable anonymity. It's not currently practical for most purposes.

Relying on a Free Software VOIP service based on the tablet preferentially for voice calls would further reduce exposure.
