The nice thing of interconnected grids is that you can route around the bad bits. There's no such thing as a global shortage of power generation. Blackouts happen when there are local shortages. Which in turn usually means problematic local suppliers and a lack of connectivity to external suppliers. The key challenge on e.g. the European grid is moving renewable over production to where the demand is. E.g. Southern Germany firing up more coal/gas when the north has ample wind production is because they lack the transport capacity (i.e. cables). Grid interconnectivity increases the profitability of renewable.
Microgrids and batteries are indeed popular in much of the developing world where grids are very unreliable and power generation lags way behind demand. India, the middle east, much of Africa, and probably South America, etc. Grids are much less reliable there and investing in private capacity is essential and something that people do as much as they can so they can keep the fridge on, their phones charged, the AC on, etc.
In developed markets, people do the same but more for cost than resilience reasons. Though I can imagine Texans might be considering both after this year.
I'm not sure what massive blackouts you are referring to. There were none where I live that I can remember; or in the years since; or before. Just not a thing in Northern Europe.
