Land value tax (LVT) and universal basic income (UBI or citizen's dividend) is not theft. Land and natural resources, by nature, belong to everyone equally. Private property is a natural institution only with regard to things we produce with our own labor. I made a spear and a makeshift shovel, those tools are naturally my property (or, more accurately, rightful possessions) because I produced them through my own labor. Man did not produce the land. The institution of private property in land and other natural resources (oil, water, mines, etc.) is an artificial institution created by society. It is a necessary institution, somewhat, but not a natural or entirely just one. When an oil company monopolizes a valuable piece of land and its natural resources, resources that they did not produce, they ought to have to pay a land value tax (or ground-rent in Thomas Paine's words) in order to compensate all the people they are excluding from access to those natural "God-given" resources. This is why LVT and UBI go together, because that tax doesn't belong to the State at all, it goes directly to the people as a compensation for being deprived of access to something that naturally belongs to everyone.

Think of land value tax and citizens dividend (UBI) this way: all citizens are part-owners of the resources of the nation. In all probability, you wouldn't pay any land value tax at all. If you just own a modest home, you pay a little in land value tax, but you receive a dividend (basic income) for your share in ownership of all the other land. Your little piece of land that you pay everyone else for is so small in comparison to the rest of land that they pay you for, so your dividend or basic income cancels out the taxes and leaves you with a surplus. The only people who would pay more than they receive in basic income is people who have own much more land (in terms of value, not necessarily physical size) than is their fair share. If you own a gold mine, then you will pay more than you receive in basic income. However, in exchange for that tax, you get the right to monopolize a freaking gold mine! You still benefit far more than you are forced to contribute, but you are asked to give a little bit back in order to compensate the people you exclude and to ensure that no one else is left impoverished while you live in luxury. Land value tax and basic income makes society much better for everyone.
