There are advantages to distributed infrastructure as well! You mentioned one of the biggest disadvantages.

I am thinking along the line of:

  - You can just do it / upgrade it etc
  - Robust against central failures for various reasons
  - Resistant to those in charge of centralized infrastructure abusing their monopoly

Utility solar is also distributed if there is enough of it installed to matter for discussion. A single installation is such a tiny share of the electric load that we can ignore if for all reasons you care about distributed. (or care about solar for that matter - it is a drop in the ocean for the environment)
