> The larger the interconnection the bigger the failure domain
True, however we have to consider the chances of a given proportion of the grid to fail: a more spread-out and heterogeneous (wind, solar...) fleet of production units is way more robust.
> power is political
True, however such incidents are rare (this one dates back from 2018) and their extent more and more reduced as grid-control devices and backup plants are continually enhanced.
As already shown there is no way for nearly all nations to ever hope to obtain an autonomous grid, and even those able to plan on this will obtain a less-robust and more expensive grid. Team play is becomes more and more mandatory and efficient, on all accounts, and bad players may lose the support of the biggest group.
> electrical prices have gone up
Yes, because there now are not enough ways to store, causing some over-pressure on existing ones. Storing in order to sustain the grid when production isn't sufficient only makes sense if we store overproduction, and overproduction remains rare (esp. at continental-level) because way too few renewable are producing. We reached the very first step: more and more overproduced renewable electricity, which triggers investments towards the next step: massive storage. V2G is a major contender.
