I had to read that twice, "crush shell and add". Dear God, the eggshell has to be one of the most horrible things for your teeth to find in food, you get that first unsettling crunch and have to first rule out it's not a filling or crown, then once extricated, you have to spend the rest of the meal with the anxiety that there could be more. Where there's smoke there's fire.

The shell is supposed to neutralize the acidity. I've always been curious if boiled coffee with egg shells actually tastes good.

Salt will neutralize acidity in very small amounts… no need for eggshells

Coffee itself isnt acidic if I recall correctly.

This recipe sounds even more complicated, basically you just smash the egg in the coffee can with the grounds and dump the whole thing into the kettle. It’s not done in separate stages.
