That's unlikely to work. You are still putting all your eggs in one basket. This seems to be a variation of the setup this company has/had.

Unless you are using different browser profiles or installations, and IP addresses for each account every single time you use them, it's very easy for Google to see that requests are coming from the same computer. If you were shut down, they would be able to do it as in the example, all accounts closed at once.

Well, it works somewhat. I keep my main email account separate from adwords, adsense, GA (although I now replaced it by Matomo, there is no reason whatsoever to use GA now), and Google Play. Ditto for their other services. I had a problem with one of the accounts a while ago - Google didn't "recognize the device" (this often happens as I have strict browser cleanup policies) and I lost access to the account because it was linked to a phone number I lost 10 years ago and forgot to change the number in the account settings. In this case, I lost access to just one account and I didn't care that much. If I used one account for everything I'd have gone mad.

People underestimate power of IP tracking. Use VPN. Plus, a must, have uBlock Origin in medium blocking mode (3p-scripts and 3p-frames blocked). Today EVERY website makes several google*.com API calls.
