That's what Georgeism is?

Lars here. I run the Center for Land Economics with Greg (we wrote the OP blog post). We are not maximalist single taxers.

Henry George was obviously a Single Taxer, but "Georgism" has a generally broader meaning than that. Some Georgists are single taxers, but not all, including Greg and I.

When we talk to elected officials, we don't even talk about Henry George all that much (I did in the ACX article series because it all started with the progress and poverty book review). We mostly speak of "Land value return" and our focus is mostly on pragmatic revenue neutral tax shifts to LVT.

And where do they advocate wholesale adoption of Georgeism? You can like one part of a theory without adopting it all.
