The moment we ask why, it has to have a reason. However Vedānta for example, would argue that brahman or the entity that is the cause of all causes, is causeless in itself. There can be no other explanation.

If something has a cause then it's ruled by cause and effect. If something is causeless, it not only does not need a reason to exist but is also the entity that puts forth cause and effect in motion. Kinda similar to Aristotle's concept of the prime mover.

A contrasting take on it afaict:

Doesn't seem much contrasting. Dao concept sounds quite similar to the concept of Dharma outlaid in Bhagavad Gita.

Wu-Wei sounds very much like Karma Yoga and Yin-Yang too. It's all very much like the teachings of the Bhagavad Gita.

Contrast the uncertain sentiment in your last comment with "has to have" and various other "facts" of questionable origin above.

It can certainly answer it, but whether it can answer it accurately is another matter.

To make it even trickier: it isn't only religious people who are affected by faith, though clever word play, cultural norms, etc can make it appear otherwise.
