Greetings, Rick: Kidding aside, there's a lot to be said for Jason's post above. If I were to have left my wallet on top of the Love's fuel pump, have I spread my financial instruments around the bike to be able to either get back home, or continue the journey? Good sidebar discussion!
This is what I carry in the VERY limited space I have aboard a 21 Fat Bob (now with 140k miles on it):
https://www.harley-davidson.com/us/en/shop/tool-kit/p/94819-02. I've added a tool for the theft deterrent screw on the seat, and a golf pencil with a few dozen winds of duct tape around it; as well, a dozen or so larger zip ties. Since I've had the heated gear pigtail poop out on me during a 22-degree Santa Sore ride last year, I've made a habit of carrying a short adapter cord that runs off the battery tender port so I have an alternate source of electrical feed for the heated gear. I also have a length of nylon strap that can be pressed into service to loosen larger tight assemblies, such as an oil filter. Finally, I recycled a sheet of thick plastic that arrived to the house in a shipping crate - trimmed it down to about 5'X4', and how have something to lay on at roadside, or cover myself when stranded roadside, and the bike cover is sitting on the kitchen table at home. That rolls up to about the diameter of a couple of pencils, and slides into the rollup toolbag.
I've photographed my registration, license, passport, and HOG membership card for the backup data source should I lose track of the hard copies (back to point A above). I've also written my bike's pin no. down, and photographed it for the cellphone gallery - not likely to remember it when the fob has failed and I'm shivering, anxious to get the bike re-started. We can call that one a memory tool...ahem...
I'll loosely refer to meds as tools here, and I keep a dozen or so ibuprofen, and a day or two worth of prescription meds in a double zip-lok bag in a discrete pocket of the tail bag. For most meds, 90% of the efficacy is good out to 15 years, so I'm feeling good about the backup plan. Thyroid meds, insulin, etc., probably wouldn't fit into such a backup plan, but... you get the idea.
Some ideas; hope they're helpful.
Safe Riding! Mark
