An outhouse doesn't actually solve the need for paper though. My backup plan of last resort is to cut up a few old t-shirts into tp-square sizes. Wipe & run them in a washer load by themselves and repeat as needed. I think I'd choose darker ones-- it's not like they'd be any cleaner after a washing, but I'd feel better about it.
In India, we'd use a water jug and do a "manual bidet" - you can even have warm water - just fill up in the sink before sitting down. You do have to use your hands but they're gonna get washed anyway.
> a month's worth of food takes less space than a month's worth of TP.
I can just barely imagine a month's worth of food fitting in the space of 3-4 TP rolls, but it would be some extremely calorically dense stuff, and if that was what I ate I likely wouldn't need much of the TP.
In other words, I can't see how this is possibly true unless you have digestive issues one way or the other.
To answer the obvious question: it's true if you buy food with sensible caloric and macronutrient density. For instance, in a space of less than one roll of TP, canned meats can supply you with a day's worth of calories - and they're just halfway on the kcal/kg scale (mayonnaise is almost three times denser). If you want a more balanced diet, store flours, pastas, canned fruits&vegs, etc. and then make meals off them.
I once did an inventory of the durable food supplies we had around the house, itemizing each product category to account for energy and macronutrients, and then boxed them all up for storage. In the end, I was surprised just how little space a month's worth supply for two takes, even allowing for a balanced diet. I recommend the exercise - especially now, as you'd probably like to know whether your buffer will last as long as you think, and whether it's balanced.

It's not the volumetrically small amount of food you're using that strikes me as curious, it's the spectacularly large amount of toilet paper. Holy shit!

Right, so, let's say 2 cans, one roll; two days, one roll. One month, 15 rolls? No. "Halfway on the scale"?" One month, 7 rolls? Maybe more likely, but I'm rounding up at every stage here, and granting you're eating only mayo.
One answer is that what comes out is a lot less calorically dense than what goes in. This isn't arbitrary--it's practically a fundamental principle of metabolism/physics.
Less isn't zero, though, and lots of life forms live on the output of others. Dung beetles, for example.
If it comes to that using leaves isn't that bad and if there is no one left to run the power plants you aren't going to want to be anywhere near the city.
Leaves are terrible. Remove the major filth using stones with flat edges. Wash the remainder with water then wash hands thoroughly with soap. Use your left hand for washing so the right hand can later be used for eating etc.
If necessary, I'll tear up an old sheet into squares, and treat them like cloth diapers. After use, toss them in a pail of dilute detergent and non-Cl bleach. When the pail is full, rinse in the toilet, a couple times, and then wash and dry.
I've lived with babies using cloth diapers. After changing a diaper, it went into the toilet. After settling the baby, you swish the diaper around with tongs, flush, and then repeat rinsing and flushing. Then you hold the rinsed diapers in a pail, for a few days, until there are enough to wash.
But sometimes you forget. And then someone gets surprised when they go to use the toilet ;)
Paper towel shortages are all around me. Ditto for tissues, baby wipes, hand wipes, etc. I can sometimes get a box or two of tissues so I've built up the equivalent of half a pack of toilet paper. My current supply of TP keeps running down and it's been two weeks since any store anywhere near me has had it.
Don't run them in the washer, just wash them out in the sink. Yeah, your hands will get dirty, but that's what soap is for and anyone who's ever dealt with a baby can tell you that it's not the end of the world.
Also, you only need one per trip that way, and you won't risk fouling the washing machine. Saves water, too.
Great idea! Yes, I think you'd have to give at least a cursory wash ahead if using the washing machine. I said washer mainly because mine has a very hot "sanitize" cycle though, so fouling shouldn't be an issue, especially if I add a little bleach to the load.
