No, as much as I hate Facebook: fuck phone numbers. The idea of using phone number as a personal identification tool is so bad, I'm struggling to believe this is not some kind of conspiracy designed for the solely purpose of mocking the user. It is bad enough that phone numbers exist at all in the eyes of the end user by the year 2019, 15 years after Skype with user-friendly logins appeared and when about a half of the planet uses the phone almost solely for the purpose of having a pocket-size internet access device anyway. But making phone numbers a passport of sorts (a proprietary, insecure, easy to lose passport, over which you have basically no control) is the worst, the most stupid/evil idea ever. And there's no way around it, it is used by (supposedly "secure") whatsapp, telegram, google, facebook, every fucking pizza delivery service and, well, basically everything else. And I hate every single person responsible for helping that happen.
Seriously, I would do everything I can to destroy fucking phone numbers, but I have no idea how can we stop this madness.
I agree with your general sentiment, but the two phrases I picked out are where you have it backward. Phone numbers are not proprietary. They're difficult to move, but if you're a customer with one phone company you can call a customer of a different phone company using a phone number.
Skype is proprietary. It belongs to a single company. Customers of Skype or Facetime or Slack or Hangout cannot simply contact each other across services.
Yes, phone numbers need to be replaced. They need to be replaced by an open solution, not a proprietary solution like Skype.
You do not own the phone number, your phone company does, and the implementation is a chip that you can physically "own" but can't control or know what happens inside.
As far as I can see the vast majority of "serious" registration schemes on the net have a phone number field which is mandatory to fill in. Mobile phone even, in some cases. You're not allowed to not have one. Soon you'll have men in black asking you what you're up to if you don't have one.

Phones are an imperfect solution for two-factor authentication but nothing else is as widely available.
There are also very well-supported ways to recover access to your phone number if the physical device is lost or stolen: Contact your phone company, present legal ID and get a new sim card.
pro tip: Telegram requires a phone number for registration, but then you don't need a phone to use it. You can link an account to a burner phone and then you can set up a password. With that password, even if the phone number get reassigned, they can't have access to your account.
> With that password, even if the phone number get reassigned, they can't have access to your account.
I wonder what happens if you acquire that phone number and decide to make it your main one. Hopefully support staff have a way of checking if the old user's active, and asking them to change their account to a number they actually have access to.
What do you suggest? Give everyone their own domain name? Phone numbers are more portable than third-party emails or logins to proprietary services like Skype. They can be moved from provider-to-provider.
