My phone number is definitely not my "most prized privacy info." If it was I'd be in trouble because there are all sorts of transactions, both digital and analog that require giving a phone number. At least in the US, if you refuse to give anyone your phone number, you'll have a hard time living a normal life. And you compare to Signal, which also requires your phone number, and uses it as the primary identifier.
