Your advice isn't bad. However, I think it gives false hope. As somone who struggled with a hereditary form of dishydrotic exzema from the age of five onwards, I can tell you that none of those things will keep it at bay on their own. You still need medical intervention. The good news is that medicine has advanced and there are new treatments which are more efficacious than steroid treatments.

I also worry your article sets suffers up for feeling they are failing because what's working for you doesn't work for them. Every case is different. What works for one person may not work for the next ten people.

Interestingly, my exzema cleared up during pregnancy. My OB speculated it might be because of the increased blood volume or hormonal shifts. 20 years later, it still hasn't returned. However, I know someone else whose exzema (which came on for them in late adolescence) didn't change during and got worse after pregnancy.
