Growth cones are only relevant during development and in regenerating neurons which are not common. Everyday neurons do however continuously extend (and contract) filopodia which may reach nearby axon terminals and eventually form a synapse, thus causing synaptic rewiring. Synaptic scaling is usually used to refer to a homeostatic and uniforum up- or down- scaling of synaptic weights and is not really relevant to rewiring.

What about hippocampal neurogenesis? Those are spewing out at a nearly constant rate all the time

  it's still a tiny amount of neurons that are being turned over. About 1.75% of the dentate gyrus is renewed per year.
