I wish it was clear from the start that they're looking at it through a pathological lens. The advice is worded as some generic fortune cookie wisdom, and I personally think that's a pretty big leap.
In general people should care about themselves and understand their impact on others. But that doesn't need to be "love", and the author seems aware of it, as the nitty gritty parts he describes are more varied than some single umbrella approach.
The "love yourself" meme has been used and abused for so long, I personally found it grating and inadequate for the people we wish to actually help. I'd wish we retire it.
