Without a ground, the equipment case, whatever the equipment is, a stove, a fan, a power hand tool, can have voltage on the part you touch and if it has nowhere to go except you then you get shocked. With a ground the breaker would trip.

So WHY can it not continue to serve both functions [other than some politician decides it shouldn't]?
The 'electricity' would continue to do the same thing it did before, wouldn't it?
A 120/240v range or dryer ALWAYS required a neutral. It was the ground that was allowed to be omitted. The neutral served both functions in an older "3-wire" setup.

Now they have to be separated and use a 4 prong cap (for those having a white (neutral) wire). Often the older appliances came with the two wires attached together.
