This really does demonstrate one of the major drawbacks if bag of holdings actually existed in the real world.
When you’re over-encumbered, you shouldn’t be able to move anymore. Or ret-con it so everything you take is miniaturized a la Capsule Corp.
Nah, if you had a bag of holding you’d get through a metal detector just fine. The items in the bag aren’t anywhere near the bag itself, so nothing would be triggered by the seemingly empty cloth bag.
