I always get downvoted for asking this but... doesn’t that seem like a really bad idea that makes you far far more vulnerable to physical crime? If a guy mugs you at an atm, the bank is going to flag something as suspicious. If a guy mugs you for your private key, you have no recourse for all of your holdings- and the getaway is a lot easier. Physical crypto crime feels like it would be very prevalent if it became “mainstream”
