I’m not a Jain so take this with a grain of salt. Their philosophy of nonviolence believes in two sets of rules - one for ascetics and one for “householders”. The former renounce everything in service of nonviolence (they often wear masks to prevent breathing in any organisms, carry canes that they use to tap the ground when they walk, etc). The latter have more “reasonable” restrictions (but are still pure vegetarians, etc). So maybe for the former group?
