You might be misunderstanding this site
I was not one of the close voters, but after reading this post and your question, I think some clarification is in order.
There is no such thing as a perfect question.
The only person guaranteed to clearly understand any question is the person who wrote it.
It is culturally appropriate to use the closure system to enforce the need for you to improve your question, even if only five people in the universe need that clarification. Stack Exchange invites rapid closure because the goal of Stack Exchange is to be a resource for many people seeking help with similar specific problems— and our Stack Exchange Overlords want quality answers. From their perspective, the more detail you, the querent, can provide (by request or by force), the better it is for Stack Exchange.
In other words, complaining that people don't understand a question that's obviously clear to you is, well... it either suggests you haven't seriously read the Tour or the Help Center to understand how Stack Exchange and this Stack work... or it's immature. Rather than arguing with anyone (no matter how much you disagree with any comment or answer), take the time to understand their perspective and use that understanding to improve your question. That's always valuable to everyone, including yourself.
And before I continue, while it's true that occasionally AlexP's rhetoric can be a little rough (look who's talking, I'm not the friendliest person myself), he's also one of the most well informed and intelligent people on this Stack. His opinion is worth considering regardless of how offended you may feel over how he expressed it. While the world isn't full of people as well qualified as AlexP (more's the pity...), it is full of people who will, occasionally or frequently, misunderstand you. Learning to deal with it in a useful manner now will help you greatly in the future. On Stack Exchange, clarity is your responsibility and believing that you're clear is no one's obligation.
Now let's move on to what I think the greatest weakness in your question is. Perhaps it's the cause of the difficulties.
- You don't understand enough about electricity.
Every point in space-time when compared to any other point in space-time has a potential difference. You're using the special case of an intentional circuit to try and rationalize a question that doesn't make as much sense as you think. Your system already allows for what you're trying to do... you just don't understand enough about the physics of electricity to realize that. Why can I make that statement? Because I'm an electrical engineer with decades of experience. Can I prove I'm right? Yup.
Lightning is, among other things, the conduction of charged particles (including electrons) to ground. High potential in the atmosphere. Low potential in the mantle. It's a complete circuit. Your magic is only replacing the meteorological conditions that create the initial atmospheric charge.
Of more practical interest is a common physics experiment where a high voltage generator is set on one side of a room and the professor holds each of two fluorescent tubes by their ends, one in each hand, pointing one toward the generator and the other away from it. They light up. It's the same principle as the lightning. High potential at the power source... circuit path through an air gap, then the lights (and the professor)... then an earth ground through another air gap on the other side. Your magic is only replacing the high energy generator.
In short, if you want a trivial example... light bulbs have two conductors. Your magic is applied to one. The other is simply connected to ground, whether that's something complicated or just a wire stuck into the earth.
If what you were trying to ask is how the magic can be applied to a circuit (e.g., must the mage touch the light bulb or can it be applied through an air gap as explained earlier?), then your question is even worse than I've interpreted. That has almost nothing to do with electricity. You have magic. Decide how it's to happen and move on (in other words, VTC:Too Story-Based).
Unfortunately, your poor understanding of electronics made the question confusing to people who don't have my background, education, and experience. One would hope that people who "don't understand the question" would choose not to answer it... except for human nature... and that's where your obligations as the querent come to bear.
Human nature is to try to help
Regardless the tone, words, whatever of any comment or answer, people are (almost always) just trying to help. It's your job to give them the benefit of any doubt. In this case, you didn't understand the situation well enough to realize you could improve your question and they didn't understand the situation well enough to see past your limitation.
But on Stack Exchange, that's your problem... not theirs. It's why the various reasons for closing questions exist.
To be frank, I've given you enough information in this post to answer your question. If what I've given you doesn't make enough sense, apply yourself to research. To expand on something already mentioned, Stack Exchange's goal is to solve specific problems and not to replace education.
If you insist on the question being reopened, then take a moment to think about what everyone has said to you and actually take the time to work through their concerns then edit your post to address them. (I realize that you've already edited the question at least once.) Thinking through people's concerns and addressing them will actually benefit you! And it puts everyone on better ground to give you the information you need.
If, on the other hand, you again believe that a future question you post needs no improvement (which is always false) and editing it continues to be offensive to you (which is always bad), you'll find your experience here painful. Per the Help Center, edits to questions are encouraged and closing questions is an expected practice to keep less useful answers from appearing via people who think they understand what you're asking.
