> Not the only one. Admittedly I don't have kids, but I'm familiar with family life and I don't think this is really that much of a problem.
Yeah, it is much of a problem. Once you get one kid, your dishwasher will be used more than merely 1/3 more, as will your laundry machine.
Every time I clean a pan or dish or fork or knife I use water, soap, and I gotta let it dry (which uses a rack which takes up space) after which I can soak up the remaining water and put it away. If I'm already doing that, it goes in one go, called dish washing or I put it in this spot where I put in a tablet and let it work for a few hours, called a dishwasher. Which is, incidentally, very space efficient and consumes very little time. I'm a proponent of reusing dishes, glasses, etc but with cats I don't find it very hygienic.
You want to wash your dishes for 5 minutes after you finished cooking your meal. Well, that's your choice. I want to cook my food, serve it with the family, and watch them enjoy the food and (potentially) receive feedback or even redo parts or grab additional spoon or sauce or whatever and perhaps most importantly for myself: enjoy the food I made, served hot, with my family. To hell I would stand 5 more minutes in the kitchen cleaning my mess up. That's for after dinner! And cleaning it up means putting it in the dishwasher.
> The idea of storing dirty dishes in a dishwasher is also just bad. You either need 10 of everything, or you are stuck digging around and hand washing some horribly encrusted pot that you need.
Then you get more pots, or you put your dishwasher on more often, or you wash the pot(s) by hand. We, or well generally my partner rather, do the latter but we also have enough pots and pans to easily last for a couple of days. They're washed in one go, not in multiple. I think time-wise, that's more efficient, regardless of you saying is better (not sure why actually).
Putting my clothes in my garden is a sure way to attract cats, thieves, and bad weather. I don't have a dryer (am considering getting one given a baby is due). Putting clothes on doors and a rack seems to work well, though does require ventilation indeed. I can also recommend to use vinegar as fabric softener.
Your advice is interesting and inspiring, even more so for road warriors and the like but its just less practical than using machines for the tough work. Why? It saves us time and effort. Time and effort is what you sorely lack when you get kids. You don't have kids, I suspect you underestimate the impact of having even one (young) child. If you have a baby you can say bye bye to your sleep rhythm. Do you think I'd love to do dishes regularly between my sleeps? No way, I'd rather have the dishwasher on, let it dry (you gotta keep it open to let it dry via environment), and be done with it.
