I trust SpaceX to figure this out.

They've already solved the hardest problem: landing a rocket upright

Fuel cost is a constant for rocketry, there is nothing to figure out there, and people tend to go through a whole bunch of checks before they are allowed to be flown on a rocket to stop them from developing some critical issue in a place where there is no way to get help or be helped. You can't do emergency medical stuff while accelerating and decelerating in a rocket and this one is doing either one almost all the time.

Ah the total trip time is at most an hour. People have been stuck longer inside NYC subway. Also on most trans-atlantic flight emegency medical diversion can easily take more than an hour.

Yes, but you're at 1G during that time. Big difference.
