Who maintains the core network if 90% of the edge is self-sufficient? That's a lot of wires to keep up if there isn't much power running through them most of the time.
To be fair - the grid is already failing in Pakistan. Adding solar to the edge is only increasing resiliency.
But in countries with functioning grids, a flight to solar could cause the same sort of user-pay funding crisis that electric cars have done for gas taxes.
There’s no funding crisis from EVs. A car that drives 12k miles/year is going to net at most ~$250 in gas tax revenue (using CA rate ~.7/gal). This can be added to the vehicle registration easy enough.
