Web$\begingroup$ I'm not familiar with this specific argument, but if you simply want to know why there does not exist a fine moduli space of stable curves it suffices to show that there exists non-trivial but isotrivial families (i.e. all fibres are isomorphic, but the total space is not isomorphic to the trivial family). $\endgroup$ – WebMumford proved that the moduli space of stable bundles of given rank and degree over a nonsingular curve is a quasiprojective algebraic variety. The cohomology of the moduli space of stable vector bundles over a curve was described by Harder & Narasimhan (1975) using algebraic geometry over finite fields and Atiyah & Bott (1983) using …
