The statement is not that these changes require legislation, though, the claim is that legislation under capitalist (presumably also socialdemocrat?) regimes will not be enough and full centralized control in the vein of China, rather than liberal democracies, is required.

Which is some delusional crap, honestly. There is obviously the capacity to enact regulation in democratic societies, and it’s obviously been put to use for the “common good”. Anarchocapitalists may disagree that it’s useful or positive, but I refuse to give them ownership over representative democracy, or to give totalitarian regimes ownership over all functional regulation.

Plus the data itself is misrepresented, but that’s a different question.
