The kinetic energy in that stardust, and the gravitational potential energy of stardust pulling itself into tighter balls, doesn’t necessarily come from fusion. There’s all sorts of cosmological forces and energy out there, and I don’t think they all trace back to nucleii smushing together.

Heavier nucleosynthesis requires neutron star collisions, so not fusion-driven. Supernovas are also when fusion stops.
