If SpaceX wanted profit, all they need to do is team up with Lockheed/Boeing, jack their prices up 100x fold and start waiting for that sweet taxpayer dollar to come rolling in. Getting prices as low as Starship is going to achieve is not a straight forward path to profit. It's like taking an industry dominated by Geo Metros being sold for high end sportscar prices, and then introducing a car that runs like a high end sports car and selling it for Geo Metro prices.

The only way they start making meaningful profit from what they're doing is basically if the exact opposite scenario of what you're implying comes to pass - that space becomes so completely accessible and utilized that they win by scale. And that's the exact opposite of 'mega yachts.' This is explicitly about exploration, colonization, mining, and more. This is about actually opening space to the human race, beyond relying on multi billion dollar toy expeditions, for the first time ever.
