Your response is retarded and full of assumptions

•you assume the keys are in the devices-an empty cold card and phone prove nothing 
•there are many reasons to leave your home, including fire
•crossing borders is but one reason 
•you assume i would cross a boarder legally 
•you assume you can buy a hardware wallet somewhere else
•you assume the gear is recognizable
•you assume this is the only backup
•i do not memorize seeds or pass phrases as those can be coerced out of you

You just sound reactionary if not jealous lol
