Art and Communication

I spotted an article written in LaTeX. It was about logic, maybe the mathematical logic.
Everything in this article was set in such an involved way that looking at the printout one could not reproduce exactly any formulae etc.

The author's idea was perhaps that only his way to set formulae (spacing, alignment) is correct. I try to imagine how being a lecturer he writes his formulae on a blackboard. Can a perfect layout of mathematics gained by TeX give more meaning or some new meaning to formula that can be written by stick on sand or by chalk on a blackboard?

If yes, why then such formulae are not published in their TeX code? What about TeX code as a language to write down formulae of mathematical logic?

If TeX is used just for precise presentation of formulae, are there any standards for correct presentation? What about the mathematical orthography?

The name of TeX is related to art. Are extremely TeX-envolved formulae a kind of art or are they just artificial? On the other hand, art is not always good for communication. (Many great artists were understood only very very late.) Even more, art is created not for communication in a common sense.

If I Were A Carpenter

If I were a carpenter
and you were a lady,
Would you marry me anyway?
Would you have my baby?

If a tinker were my trade
would you still find me,
carrin' the pots I made,
followin' behind me.

Save my love through loneliness,
Save my love for sorrow,
I'm given you my onliness,
Come give your tomorrow.

If I worked my hands in wood,
Would you still love me?
Answer me babe, "Yes I would,
I'll put you above me."

If I were a miller
at a mill wheel grinding,
would you miss your color box,
and your soft shoe shining?

If I were a carpenter
and you were a lady,
Would you marry me anyway?
Would you have my baby?
Would you marry anyway?
Would you have my baby?
