Google has the power to fire me from my job by deleting my Google account.
I don't know why that would be the case, but let's say it is.
An overzealous cop and prosecutor can, with a little luck, use the power of the state to get you executed or imprisoned for life for a crime you didn't commit.
If you had to choose one of those, which one would you prefer?
Even if they did delete it, why not just make another one?
Google Accounts aren't linked at birth, and many people don't even have one.
