so how can we make progress?

While we're at it, canonicalizing paths at creation time seems wrong
also:
First because those two expressions do not return the same thing:
Path from: 'a/b/c/../d'
Path * / 'a' / 'b' / 'c' / '..' / 'd'
Second because if c happens to be a symlink, then the operating system
will not find the same thing as Pharo. The semantics is that you
follow the symlink first, and follow .. in the directory you end up
in. So that goes to the parent of the actual directory pointed to by
the symlink, not back one level in the path.

All this already works (although maybe not perfectly in edge
cases). Consider:
'file:///C:/Users/tempfile.txt' asUrl.
'file:///C:/Users/tempfile.txt' asUrl asFileReference.
FileLocator C / 'Users' / 'tmpfile.txt'.
Where the last two are identical.
Note that relative file URLs do not exist.
