This is literally what people said about high speed rail. The argument was that this is simply not cost effective and that’s why it can’t be built. Yet, China covered the whole country with HSR in a decade. Short term cost effectiveness isn’t really an issue when you have a state directed economy. And costs for any new technology come down over time. Maybe China will start using it for ground based transportation first, and then start using it for other applications. We’ll just wait and see.
