I am very comfortable eating stoveless as I dislike the hassle of cooking if it's just me (I enjoy the social aspect of cooking with others). I wouldn't do the cold soaking thing though. It's pretty easy to just choose foods that you can eat without prep, especially if you can hit a store on a daily basis. Starbucks has a pretty good Via iced coffee mix that I put in a water bottle and drink for my caffeine fix.
I think it's a lot like camping. Some people want to do it and others don't and insist on the hotel experience. Of course staying in a hotel is "more pleasant" than camping but (for me) there is a sense of satisfaction in knowing I can rough it once in a while. Same with eating stoveless on a bike trip.
Longer term off the grid would be more of a challenge. I'm down to a SS cup/pot, can opener, spoon and small stove for a basic kitchen. Ahead of time I break down foods like mashed potatoes, couscous, oatmeal, ramen etc... into individual serving size vacuum sealed sandwiche bags and calculate how much water to add to them. On the road I just boil water, split it between a drink and meal and add it to the bag - and eat out of the bag too. No dishes to wash and trash is pretty compact (all goes in one of the sandwiche bags). It's a very efficient way to package food as well as the sandwiche bags conform to the shape of whatever container one is using for food storage.
