I was going to ask if you were counting ounces but it looks like you are counting grams. Yikes. I am all for minimal but dang. My brother cuts every strap to absolute minimum length, his tent is paracord with a plastic sheet, has modern lightweight clothing, etc… His emergency kits are like yours, but maybe a bit more. May I suggest someone carrying a venom extractor for bug bites, wasp stings, or snake bites… If the light you are looking for is truly emergency use only, a AAA seems okay to me, but AA makes more sense in almost all scenarios.
