> Again, it's not. The smartphone is used as a single authorised device. Gasoline works regardless of which station you purchase it from. Out of petrol? Fill it up at the nearby station and carry on. Or preferably, don't let it run out in the first place. A mobile phone works regardless of which store you purchase it from. Lost your phone? Pickup a new one at a nearby store and carry on. Or preferably, don't lose it in the first place.

Again, a mobile phone works regardless of where you purchase it. Your banking systems, etc are not authorised to a mobile phone, though. They're authorised to the one mobile phone that was authenticated. It's not enough to buy a new phone. You need to contact every single service that's bound to the lost/stolen/broken phone and authorise the new one before you can use their services. In the case of the car, it's enough to just fill up the tank with petrol purchased anywhere. It's ready to carry on at that point.

  Not clear your meaning. Are you referring to the mobile phone being used during 2FA auth flows? In this case, the authorization is not to a device but rather to a number on the cellular network. You can swap devices without your bank knowing and without disrupting your authorization. Are you referring to mobile banking apps? If so, again, the bank is not authorizing an individual device. The authorization is a sign in session on the app. You can swap phones and download the app very easily without contacting the bank. > It's not enough to buy a new phone. You need to contact every single service that's bound to the lost/stolen/broken phone and authorize the new one before you can use their services. Are you referring to changing phone numbers maybe? If so, that is a totally different topic from OP and also from my comments.
