Sure, the covariance between solar and wind production at one site isn't 1; and the covariance between all the contributing sites for wind isn't 1. So it does smooth out to some extent. (To some extent-- there are practical limits on grid size).
However, it's inescapable that you need a whole lot of storage. As we conceptualize it now, the grid has to remain available during 1% and 0.1% events.
Again, your point is orthogonal to what was said. If someone grouses about storage, mentioning a net exporter provides zero information. Mentioning that my house is a net exporter does nothing to inform them.
