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.
