However that could creates some creativity in place and create similar, but different (better? Worse? Who knows) products.
Compare this to Coca Cola in Germany during WW2. Due to the embargos they couldn't deliver the "secret syrup" so Coca Cola Germany used some "fantasy" and created (the predecessor of) Fanta, which nowadays is a brand of Coca Cola served in multiple countries (with differeing recipes)
Fanta is now nothing special either, just a sugary fizzy drink with orange flavoring that can be done better by other local companies.
Coca Cola is just a branding and marketing juggernaut at this point, but their drinks themselves are easily replaceable by better local alternatives at any time.
Come to think of it, banning Coca-Cola could actually be a health benefit for the population lol.
I remember that in Mexico there are poor villages addicted to Coca-Cola where the company uses local water to make the drinks and the villagers have no access to clean tap water and have obesity and diabetes from all the coke they drink, and all is sponsored buy the Coca-Cola and their lobbying. Absolutely disgusting.
I myself spend some time in bread and a part of the taste of bread comes from my bacteria/yeast culture growing here at my place, feeding of stuff which is in the air at my place. If i go elsewhere that already changes to a small degree. If I vary temperature, humidity of air ... this has impact. On industrial scale the impacts are way more as they use processes to ensure the end product stays as much the same as possible independently from changes to ingredients (natural products change with each harvest ...) and where it is processed further (a Big Mac is, by McD, supposed to be as equal lgibally as possible) this is done by having Enzyms, chemicals and other comments doing their work.
