Assuming you’re talking about the “no brown m&ms” clause that Van Halen had as part of their tour contract. If so, you might not know that it may have been a form of quality control. Van Halen had a big and complex stage show. A typical show would use 3 18-wheeler trucks, Van Halen would use 9 of them.
The complex contract ensured that they had a stage that could support all the weight of the Van Halen show. That any overhead girders were sturdy enough to hang the things they needed to hang. That the electrical system in the venue could support all their equipment. That the doors were big enough to allow the equipment to be pushed through, etc.
If the band went backstage and saw there were brown m&ms in the bowl, they’d know that the venue hadn’t carefully read the contract, so they’d need to double check everything else.
There’s no upside or downside to setting a tariff on uninhabited islands. Why not include Atlantis just in case? Why not also set a tariff on Mars, Venus or Pluto just to be sure? Why not also include Middle Earth and Vulcan in case they turn out to be real?
If all they wanted was to ensure that every place in the world was covered, they could have just said that the standard tariff rate was 10%. What’s more likely is they used an LLM to generate a list of every place on earth and just put a 10% next to it, showing how unserious they are.
