capitalists would have found a way to stop him
I don't think capitalists can be counted on as a rational actor in this case. Musk certainly has a lot of ventures that rely on imported goods and materials, but he is literally too ideological and short-sighted to see how tariffs will impact him, and he's not the only one.
I think that the modern practice of astrology is intentionally vague on this point because you're supposed to fill in the blank yourself. Whether you believe in psychic energy or spiritual power or guardian angels, you can nevertheless participate in astrology and most importantly purchase astrological tchotchkes ranging from telescopes to tarot cards to shiny crystals.
