What if carriers created an "enhanced security mode," which users can opt-in to if they want more security and are okay with sacrificing convenience in case of account recovery? It would be similar to the account recovery aspect of Google's Advanced Protection Program: "A common way that hackers try to access your account is by impersonating you and pretending they have been locked out of your account. To give you the strongest protection against this type of fraudulent account access, Advanced Protection adds extra steps to verify your identity during the account recovery process. If you ever lose access to your account and both of your Security Keys, these added verification requirements will take a few days to restore access to your account."[1] [1] https://landing.google.com/advancedprotection https://landing.google.com/advancedprotection
