You and teachers live in the ideal world where are the ideal capacitors.

Leyden jar has insulator made of glass.
It is possible to make it with insulator "made" of the air.

What will be leakage in such case?

So after you saying he lives in a world of ideal capacitors you now
proclaim that a Leyden Jar is an ideal capacitor? Pot, kettle.

Because it's not a real world "practical and useful in actual devices"
capacitor, Leyden Jars inhale vacuum like almost nothing else in the
capacitor universe. They are useless in virtually all practical
applications.

So Leyden Jars normally occupy the absolute bottom of the capacitor list.
