While I agree, there are so many other traditions that make much more sense than astrology. Meditation, quiet shrines with incense in groves, yoga, taichi etc. And they are not at odds with scientific temperament.
Once secularism changes peoples beliefs, no one is actually in control to decide what they choose to replace it with. They might choose yoga, they might choose astrology, or they might choose qanon. Nietzsche and other philosophers talked about these problems a lot, but most this society failed at the task of living up to what was needed(ie society as a whole guiding peoples and establishing healthy alternatives).
