The thing about microgrids is that maintenance falls onto the owner. You still require specialized knowledge and perhaps team of people who can handle it to maintain the microgrid and repair it. You still require supply chains for the complicated parts that cannot be easily replaced, mostly batteries and inverters. In a shortage situation, central grids will be under pressure to be fixed immediately, but your single set of wind turbines or solar panels might not be. So the way I see it, microgrids would be maintained by cities and communities instead. The level of distribution would make it similar in action to the times of old coal power plants, one per city.
