I agree, really, a lot of questions which use copy tag are in low quality.
(I just clicked on tag and checked the first page of questions.)
But there are some obstacles:

• A lot of Excel questions (like this,this,this...) where copy is not related to file-copy (yes, you mentioned them as "The worse thing...").
• Issues with copy command in command line (like this and this), where file-copy tag will be more generic and xcopy and robocopy can not replace it.
• And a new software called Copy cloud storage (this question).

Adding a tag like copy-app or copy-cloud-storage can somehow solve problem with Copy cloud.

But what to do with that Excel questions?
Add new tags like excel-copy or copy-in-excel? Leaving these questions without copy is not a good idea, and replacing them with file-copy is wrong - a big headache.
