gearing up

As a study in preparedness or perhaps just outright silliness,
I've been conducting a mind experiment,

trying to figure out what gear one would need in order to survive as a wandering temple artist in a slightly hostile world. I keep thinking soap might be necessary, I like soap but it also seems kinda decadent, what about salt?
...hmmm... so many possibilities.
See anything I've forgotten?
Have you any suggestions?

water water everywhere...

How much do you use?

Looks like I use about 595 cubic meters per year.
I think being a vegetarian probably makes a big difference.
