Do hydraulics folks use electrical analogs to study their craft. No? Then why should folks studying electronics use hydraulic analogies for their studies? Why not accept that a capacitor is charged with energy or energized, and study capacitors using energy as a quantity? The bucket brigade does not take into consideration that a capacitor will only accept a limited amount of energy/<charge imbalance>, and then will block the flow of charge or storage of energy; whereas a bucket of water will simply overflow and not block the water flow.

Yes I agree .... The water analogy fails VERY quickly.
To answer your question, the reason that I ( Me, personally ) think of the classic water analogy, is that it helps me to visualize the problem, which is the way I learn complex concepts best.
Seriously, you would be much better off in the long run learning the proper terms and processes.
As there will come a time when you fund you have to unlearn all those bad/failing ways and finally learn the proper way.
That's going to cause confusion. You are better off starting the correct way from the beginning
