SMS is not secure, that's why. Police have used special devices to intercept messages on a broad scale without any warrent, which means individuals can too. Service providers are well known to send "replacement" sim cards out to people who then use it to access 2FA accounts. Happened to H3H3 on YouTube. Phone numbers in general are insecure. There is no enforced verification system - people can receive calls from their own phone number, and people can fake the presented numbers. There is such a significant amount of spam callers as well. The FCC doesnt care. The entire phone system in the U.S. needs to be remade with security, but powers that be really don't want that.
