I can kinda get it not being “murderous”. When civilians are killed while in the middle of a war, it’s not considered murder, it’s considered a war crime. It’s a technicality, but that’s how words work.
But I’m not sure how you can say it isn’t brutal. Of course it’s brutal.
Alfalfa Meal and Coffee Grounds - can only be used in moderation due to their high nitrogen content which would fuck up waterways way more than salt.
Beet Juice - not nearly as effective as salt
Grape Skin - still in testing, no where near close to market, unknown ecological impacts
Brine - has the same problem as salt because that’s essentially what it is
Manual removal - are you fucking kidding me?
Salt is the best we have, and the alternatives aren’t just less economical, they’re also just plain unfeasible.
