Rocket launch demand is growing like crazy. The market is not competitive. And if SpaceX doesn't fuck up, it likely never will be. In that kind of market, margins will be impressive.
Personally, I'd never live somewhere where a car is mandatory.
On a long enough timeline the world normalizes. These classifications of "first world" vs. "third world" countries can be viewed as an ordering of arrival to the modern high-energy high-tech life. Third-world countries don't stay in mud huts indefinitely. China is the fastest growing automotive market in the world, it wasn't too long ago they were riding bicycles in droves. Now we're hearing about manufacturing migrating from China to India where it's still cheap, the cycle repeats.
I don't think we can say that everyone in the world will ever be in the market for SpaceX products and services. But we can definitely say that's possible about electric vehicles. They are already often owned and operated by individuals, and the common utility is incredibly obvious.
All I'm hearing in your comment is that they're currently too expensive for most people. The price will decrease as the economies of scale take over, the buying power and interest across the world population will increase in spurts, it's only a matter of time.
Once EV-capable batteries are as commonplace as propane tanks, this picture is going to change dramatically. Eliminating a transmission and ICE from a vehicle design substantially lowers the cost to manufacture it. There's very little precision machining left in an EV, it's basically the steering rack, and myriad ball/roller bearings, wheel hubs, brake rotors and calipers, what else? It's a big difference.
I could afford to buy a car, but I have an amazing electric bike, and live in a city with fantastic public transport. The 5 days a year I actually NEED a car, I can just rent one. So why buy?
