This isn't about losing your phone or someone else being able to access it.
It is about cloning your SIM card without you knowing it. It's another step 'hackers' have taken in social engineering over the last 2 years or so. They will call your mobile provider and acquire a SIM card with your phone number and then you are fucked. T-Mobile recently changed how easy it is to acquire SIM cards after big youtubers and twitch streamers got hacked that way.
It's also why pretty much all banks in Europe offer a hardware generator for online banking. Many of them still offer 2 step via phones but it is not recommended anymore.
It's a start for Sony but they should be working on getting Authenticator app support asap.
In fairness, this requires alot more knowledge of the person and is far more a targeted attack than the typical PSN scam.
There is a pretty big gulf between the typical script kiddie who catches a few passwords via phishing and organised identity theft.
