The distribution becomes the target, not the generation. I agree with most of the other things you're saying, about how I can generate a small amount of electricity on my own if I buy a PV system. That's irrelevant, however.
Destroy oil supply and there is a crisis in 12h. Destroy solar supply and there's a crisis in... 20 years? It'd actually be much sooner but the point is that it's much less urgent that oil.
