I'm not sure that was the point of the poster's question about electricity, because I've heard the same assertion made by science writers and such.

Our current BFF, ChatGPT, says the question is about "charge" in that we don't know why particles have a charge. So what is a "charge" and why? Gravity is also presented as a thing we don't fundamentally (ontologically) know about. Interesting!

And not disagreeing with the desire to keep asking, nor with the desire to find a final answer. The author of the article puts it fairly well:

We don’t have philosophically satisfying insights into the universe at subatomic scales...there’s no straightforward explanation of what a bound electron actually does: it’s not orbiting the nucleus or spinning around its own axis in any conventional sense. Most simply, it just exists as a particular distribution of an electrostatic field in space.

The answer to "why?" has to stop somewhere.

Why?
