>In the instance of perfect elasticity of the demand or perfect inelasticity of the supply, the price will remain the same and the entire tax burden is on producers. An example of perfect inelastic supply curve is unimproved land (the supply of improved land is elastic because more or less could be created by investment in improvements) or crude oil. Thus, the whole tax burden is on landowners and owners of the oil.

It's literally econ 101 that says landowners will bear the burden of a land value tax.
Supply of land is perfectly inelastic and land value tax is not a marginal cost of production so does not change MR=MC.
