I really don't understand how ethnicity or provenance has anything to do with this. This is a philosophy book from more than 2000 years ago, the person(s) that wrote it is as different to today's Chinese as to westerners or anyone else. It just talks about the human condition and as such anyone can relate to it.
And about the appeal of Daoism versus, for example, Buddhism I would refer to this https://en.wikipedia.org/wiki/Vinegar_tasters. Laozi just smiles, Daoist writings have a kind of humor and lightheartedness to them that make them much more appealing to me. I don't concern myself with enlightenment, I just want to smile.
The great Tao is broad and plain
But people like the side paths
Does a long history of Taoism and all the traditions and beliefs that arise around it make it easier to discern the Tao?It's a very accessible exploration of attachment and offers some great insights on things like ego, virtue and leadership.
Your dismissive tone is curious because the same kind of dismissal can be made of the absurd and outlandish belief systems and mythologies of Mahayana. "Perfected wisdom" is hard to imagine when basing it on stories of stories of myths of god-like beings.
I get the pragmatism coming from a Buddhist, but not everything can or indeed needs to be brought down into a "path". I'm sure you are fully aware of this.
Now I am fascinated by your consternations. Whatever the answer, whatever people get out of it. What's it to you?
A somewhat out of place critique coming from a lack of understanding IMO.
