Why is XRP designed to be $10,000?

I'm somewhat perplexed about the design of XRP's value. Why was it initially set to be $10,000? This seems like a significant figure, and I'm wondering if there's a specific reason behind this choice. Is it tied to some underlying economic principle or market analysis? Or was it just a random number plucked out of the air? I'm interested in understanding the rationale behind this decision, as it seems to have a profound impact on the cryptocurrency's market positioning and adoption.
