I was wondering... why every field has it's own alias but never used it?

For that stage that makes query more cluttered so why even bother? For good practice?

The aliases are used to give column names to the function results.

These aren't just fields being selected, but the results of functions being performed on fields. If you don't give a computed column an alias, the header for that column will show the formula itself (rather ugly).
