I read GP as talking about the positive impact on GDP of rebuilding, and with the intent of pointing out that GDP is a flawed metric.

I forgot about this and had a busy week, but yes you nailed it. The other commenters are also right in pointing out the obvious flaws of GDP with or without meaning to, but you understood the spirit of the comment.

Not really. It means spending money rebuilding things just to maintain productivity is instead of investing in productivity multipliers.
