I like sesame. Should sesame be banned world wide because 0-5% are allergic to it? (I assume: no) Can company choose to produce sesame products? (I assume: yes) Can company choose solely sesame products, without doing sesame-free stuff? (I assume: yes) If new regulation comes along, and business deems new requirement is unacceptably high, can it pivot to a different market where it can reuse same investments? (I assume: yes) Law can be flawed. (Because people definitely are) Maybe it can be improved? E.g. require random testing, and then say there are 7 seeds in every 100000 of pies.
