Why do we need Legendre transformation for thermodynamic potentials?
If we didn't use Legendre transform, we would waste precious information. Consider the case of a function of one variable for simplicity: $y=g(x)$. Now what you propose to do is to define $t=\frac{dg} …

Why do we need Legendre transformation for thermodynamic potentials?
For example, temperature is much easier to control. This is why Helmoltz free energy is introduced: $F=F(T,V,N)$ having in mind that $T=\left(\frac{\partial U}{\partial S}(S,V,N)\right)_{V,N}$. …
