Request to reopen my question "What is the use of the $\ell^2$ spaces?". It was once closed as lacking context, but was reopened after the context was added. Then it was closed for "This question needs to be more focused". It is more narrowly focused than the other questions which is not closed (example). I further narrowed the focus to $p=2$, but it was left closed in review. I focused even more narrowly to $\mathbb{K}=\mathbb{R}$. There is no close-voter explaining how narrow is enough.
It is almost José Carlos Santos and Another User who are trying to close this question and they leave no comments.
