This has nothing to do with IP laws, and everything to do with baby formula laws. You don't seriously think that without the ability to sell the recipe, nobody would invent a safe and effective baby formula, right?
If you have two brands of baby formula, Death brand that kills babies, and OK brand that is perfectly fine, and you start putting Death brand in fake cans labeled OK brand - that is absolutely an IP enforcement issue. The desire of OK brand to protect their brand, and profits, combined with reasonable IP laws allows them to lead enforcement actions and protect consumers.
The kind of intellectual property we are talking about is the one where Death isn't allowed to make baby formula that doesn't kill babies, because OK patented making baby formula that doesn't kill babies and won't give them a license.
This is a matter of trademark, which is completely orthogonal to copyright and nobody is protesting against it here.
