@d6 I disagree with the point of the article. The personal habits of even the very richest individuals *can't* significantly affect the bottom line. So any effort or political capital expended on fighting the owners of 23 superyachts would be better spent on something that matters.

Imagine a billionaire who could be convinced move the levers of industry to reduce global cement production by 0.01%, but only in return for permission to operate a second superyacht. That would be a large net win.

Superyachts may be part of a big problem, but not this particular big problem.
