You are ignoring that income taxes and other taxes reduce land rents. You can't tax the same dollar twice after all. The entire reasoning behind a single tax system is that every dollar is taxed through land value taxes in this case.

Yes this does mean that renting/owning low density housing will be more expensive but your income will be much higher to begin with as it isn't taxed.

For example 20% VAT and 30% income tax mean 56% of your money can be spent on housing. Without those taxes you will have almost twice as much money to spend which means you can afford higher land value taxes and if you decrease the amount of land you use, your effective tax burden will go down but so do the costs to maintain infrastructure and other public services.
