the issue is you don't have the luxury to type the passcode from the security of your home all the time. You have to type it while outside, cameras and other ppl being around. Even if you have a alphanumeric password as passcode, it can't be too complex because you have to remember it and type it (password manager is behind this lock). And as soon as someone can record you typing the password, they can now steal your phone and ruin everything.
