The Earth and all it offers freely to its inhabitants is humanity's commons. Who can claim to be exclusive owner of even a miniscule part of the Earth or its resources without paying respect to the equal right of all other Earth inhabitants to the same? The value of land expresses the social demand of the community at large for access to specifically located spaces and resources. This value or "rent" of land, which when land is privatized expresses what an "owner" can charge others for access, is really a social value which can and must in justice be collected as the only legitimate obligatory payment to the State. Having done so, we might then abolish all other taxation on labor and commerce, etc, and thus free all of productive labor from bearing the unfair double tax burden of private land rent and public confiscation of production. We only need collect land rent to socialize all the wealth we need to build communal infrastructures of any magnitude. By communalizing (monopolistic) land rent, privatizing wages and compensation to productive capital, we will have created a just distribution of wealth in the community because the values created communally would be communal and the values created privately would be private, as they should be. This is basic justice which we all hope our own children learn to understand. What is mine is mine, what is yours is yours, and what is neither mine nor yours, must be treated as ours, ie, must be shared equitably, or there will be trouble in the sandbox. So, why don't we adults get it right for the sake of our children and start sharing the communally created values of the Earth fairly?
