The crew dragon is designed to be completely autonomous. 99% of the time, the astronaut is just a passenger, so there is less requirement for physical controls.

In terms of mission control telling you to press X button, it is almost certain that mission control would have a simulation of the cockpit running that would show them exactly what the astronaut is seeing on their display. So they will always be able to direct the astronaut correctly.

I definitely think a touch screen in this situation can be safer, because it can display information in a way that makes it quicker for the astronaut to understand the situation. It in theory requires less training because there is less requirement to remember the position and function of every single switch.

Space missions need to account for the times when things really hit the fan, that's when design really matters. If shit goes haywire why should I assume my touchscreen is now displaying the same thing as mission controls? If it's not then instructions go out the window. If shit goes haywire in the shuttle, mission control can safely assume they're looking at the EXACT control scheme the pilot is, and can read out controls accordingly. I get that automation is intended, but for emergencies a touch screen really doesn't cut it.
