For a GHB, I don't think you really need so many cookware items to haul around. Better replace them with the ready to eat food if the weight is not a concern. The steel bottle is all what you might ever need for a makeshift cooking, chocolate mixing, or water treatment (by the way I love your idea of a long spoon to match the bottle!).

Clothes - consider sturdy work gloves, perhaps of a thick leather to handle hot stuff. Kudos on Balaclava! It's the best piece of survival clothing to have - extremely versatile. Depending on your path consider some lightweight overboots (i.e Tyvek) great to traverse muddy trails.

For the self defense, the padlock on a bandanna is redundant if you don't really need one to use with a locker. You might already have even better "heavy piece on a rope" to secure your bike at the street. Personally, the only bag I'm EDCing now is a small sturdy rip-stop nylon bag, collapsing into very small pouch when not needed. In case I need an impact weapon, I can quickly load it with hard, pointy, and heavy stuff in my pockets (i.e. you can use that steel bottle full of water for that). It's much better than a bandanna in combative handling as well. Such a bag is also good to have if you plan on foraging/scavenging along the way. In fact, it's my lunch bag, but also it works well as a folding umbrella drip stopper, and handy at the shops, after the plastic bags ban was enforced in California, it fits up to 4 six-packs easily Also a high lumen blinding flashlight can be considered a self defense item even if without "tactical" features.

I didn't notice any emergency power supply to charge your phone and flashlights on the list. A 10 A/h Lithium USB brick should be sufficient, but not sure what your flashlights take. Maybe you'd better go with something like a 4AA GoalZero Guide 10.
