TAG view is only as good as the metadata associated with the contents of the library.

A good solid hit on the head of the nail there. Just add to that the concept that your folder structure is also metadata and you'll soon find tag and album views to be your friend (instead of the artist folder, you can use the artist tag).
Observation one: The genre column can be hidden (see preferences) and unless/until you have your genre tags sorted out you can hide it and get the space back for useful information.
Observation two: If your Artist/Album tags are out of whack, there are a multitude of software that can sort that for you. MusicBrainz Picard has a "folders to tags" option, and there are others (such as bliss) that can do all sorts of tagging automagically based on rules you define.
Observation three: Don't tackle all your tags at once. Concentrate on Artist/Album first, including how you want to handle multi artist albums (because you can be cleverer with tags than with folders in this case).
