Couldn't the camera sensor be turned on and off at will?

The same reason we hang up cell phone calls. The term means something that people are familiar with and the end result is the same, so we keep using the same terminology even if it isn't literally accurate due to changing technology.

There is still physical shutter to protect the sensor from dust when changing lenses.
