Subjective list question?

The latest HNQ is, in my eyes, subjective:

So, how would you explain the concept of a variable to a 9 year old

(the actual question in the post, emphasis mine)

This is quite subjective. I see the 20 answers it has accumulated in 23 hours as strong indication that viewers¹, who might or might not be educators at all, are the majority of the answerers.

On top of that, I can't see a way to evaluate the 15 answers that have a score of $x$, with $-3\leq x \leq 3$. If I remember the definition of list questions, this qualifies. The question doesn't exactly give some way to know which answer is better.

Unlike some other teaching-analogy questions, (actually, at the time of writing, the question isn't tagged with that tag anyway) this one actually says quite bluntly that a possible solution

doesn't feel correct.

(emphasis not mine).

My question is an attempt to see where consensus lies today, regarding these matters.

How might such questions be treated? Are they subjective? are they good questions that need editing? Are they good as-is?

So, what are the community's thoughts on this? Let's try to reach consensus on what to do with such questions (i.e. ones that reach such a high deviation in the answers)

¹I don't say users, because it's a HNQ, so some if not most of the answerers answered because they saw it in the sidebar
