I left the shared dorm kitchen behind when I graduated university. I prefer not to go back. I'd rather my kitchen be my own. Have you lived in a shared communal space where everyone uses the space but no one takes the time to clean? Try reigning those people in for me. No thanks.

Cooking to scale is also not a problem if you know what you're doing in the kitchen. Smaller kitchens and a lack of proper hardware can make cooking more challenging, but it's super easy to scale a recipe up and store away the extra portions. There are entire communities dedicated to meal prep tips and strategies.

It more comes down to training and time for most people, not a lack of hardware.
