Karl Marx had a lot of great ideas that have been integrated into our modern liberal democracies (antitrust laws, labor unions, public schooling, etc). One can have a nuanced discussion of Das Kapital without being a communist. If you assume otherwise, that's your own cognitive blind spot.

I never said communist. But yes, you can pick and choose ideas from different thinkers. That said, what Nevermark wrote fits squarely within orthodox Georgeism.

They're free to prove me wrong by saying that they're in favour of sales tax or income tax or capital gains tax. That would prove to me that they're just taking the idea that "land value tax is good" without buying into Georgeism as a whole. But I'm confident we'll never see such a comment.
