That's overly judgemental. In the environment where shells originated,
not being able to easily put spaces in file names wasn't considered a
problem. File names weren't thought of as names in the natural language
sense, but as identifiers in the programming sense.

You don't complain that you can't put spaces in identifiers in a
Python program, do you? No, because that would require all identifiers
to be quoted somehow, which would drive you crazy. In the same way,
requiring all filenames to be quoted would drive shell users crazy.
