Tags are great BUT

It's pretty important to realize that a files position is merely it's default tag (and you can tag it further with many different types of systems like extended attributes, as I think both Gnome and KDE have used at times).

Without that default tag you have a mess.

It's also important to note that Tags have a very high maintenance cost of their own.

Duplicate, inconsistently applied and redundant tags are a aggressive cancer in any of these systems.

No you can't just ignore them as they make it more and more difficult to accomplish even basic viewing /scanning over files for the system and the user.

Many many users have trouble even doing basic maintenance on their file locations (that default tag) that makes a tag based system even more prone to failure.
