Ok cool, so whenever you register on a new service, you have to add all 4 of them, which means going to "other safe places", picking tokens, adding them, and placing them back. Also I doubt your safe places are as safe as bricking them into the wall. Apparently it's okay for you, so, keep it up then. I personally hate this. Also having 4 tokens does feel kinda too much to me. Each additional device does open a new attack vector, and if your token at home or in other places suddenly disappears, you're unlikely to even notice that quickly, while an attacker could use that time having a token. Also, if the service doesn't support having multiple tokens (as mentioned in comments, Twitter is such an example), then having 4 tokens doesn't help much.
