How is the resistance provided by turbulence ultimately overcome to allow final collapse?

Answer

When the turbulent energy dissipates through viscous heating or the scale of motion becomes too small.

Turbulence provides kinetic energy support that must be reduced, either by the energy bleeding away through viscous processes or because the chaotic motions are dwarfed by the large-scale gravitational contraction.
