Not to pester too much, but georgism, philosophically, seems entirely based in an attempt to find some liberal justification for a broad solution to many problems. It attempts to find some legal method within the assumptions of the capitalist system (ownership as it exists in capitalism being key) to mitigate the problems that the original assumption creates. Capitalism will just react and reform to its benefit around those new mitigations systems like it always does. But the georgists ideas remain limited to the set of possibilities that capitalists have limited debate to.
