The Iberian blackout resulted from a way deeper and more complex reasons than your comment implies, and does not yet have a complete explanation.

The "inertia" issues already have solutions being used in production (in Australia, for example).

Oh it was extremely complex and I didn't intend to imply that the full explanation would fit in a single HN comment.

The inertia problem you mention wasn't solved in Spain though, and whether it can be solved or already is elsewhere is irrelevant here.
