- fucking annoying
- can't believe they sold people that it's BETTER to have to get your phone out to login
- incredibly annoying

You can, the concern here is with people, not the specifications of SMS. People can be social engineered to give control of your phone number to someone else. It's happened before, it's not a hypothetical, and it's why security experts advise against using phone based methods.
Im pretty sure that you would realize something was wrong with your phone then and its useless to them 2factor wise unless they have your password.
