Reasons to switch from pocket carry to backpack/purse/murse edc:

ETS players can be readily identified by their bulging pockets, exposing them to prepper profiling.

Pocket overload causes premature wear on clothing pocket surfaces.

Full-figured pocket packers may need to apply vaseline to doorways and hallways to permit passage (personal experience-YMMV}.

Constant jostling of pocket contents damages edc items.

Pocket weight may necessitate belt plus suspenders trouser suspension.

Gravitational pull on pocket contents may result in belt/suspender failure, limiting options for fight/flight response.
