So... what's your phone #?
Or do you believe when you give your phone number to Google, it's obfuscated, not indexed or searchable, and not permanently associated with you for their current or future use?
Next step - has anyone confirmed your identity yet?
It doesn't matter the technical details of whether the number is easier to search, it's the intent I find disturbing about this.

No, it's to point out that once your privacy has been compromised, you might not be able to undo the damage.
