Here is my best argument for why a layperson should go raw: it forbids you anything that even resembles junk food. Raw may be flawed but clearly it's way healthier than how most people eat. You can say it's a crutch or psychosomatic or whatever but for me once I got into the mindset of it I just stopped noticing unhealthy food. Almost everything in the modern dining world is cooked.
The major downside - because it's so damn restrictive (plus we're practically vegan) is that raw gets to be time consuming. It's really impractical for people on-the-go. Sure you can always just eat an apple or some carrots but that gets boring and so you end up dehydrating your own bread etc and turning down practically every social dining opportunity. In a way that is a Good Thing because there is a lot of harmful junk in modern food, right? But it takes real dedication and eventually we decided a totally raw intake just wasn't worth all the effort.
A cooked food diet opens up the floodgates to all sorts of unhealthy temptations. But in the end it came down to priorities like convenience. If you're thinking of going raw your best friend is the blender: there are a million nutritious ways to mix a surprisingly delicious smoothie (secret ingredient: jalepeños).

What do I think of roofless habitat, living in nature as God/FSM intended and having sunflowers for a pillow?
What do I think of human-fur as an alternative to soul constraining fabrics that bind me in slavery to my own comforts.
Also, when dipped in animal fat, your nails can be strengthened to sharp claws for defense and excellent hunting tools.
These are extremist ways to alter one's lifestyle, and it's usually done by people who want MORE than they already have, not people who are forced by circumstances to eat raw foods, or sleep 2 hours a day, or work 4 hours a week or only consume liquid diets.
And from my experience, people susceptible to these fads make for awful companions and hangout buddies. Sure, Voltaire might have advocated for the Noble Savage who lived in harmony with nature, but the SOB was writing praises to nature and animal-like living when he was himself collecting royalties, living in castles and rubbing shoulders with European nobility.
I lost weight, I was often hungry, and I couldn't stop craving meats and cheeses. When I looked at pictures of people that were also on the raw diet, they looked gaunt and unhealthy. So I decided it was all bullshit and gave it up.
Personally, I think there are better diets.
