So as a Georgist (followers of Henry George), I believe most form of taxation is immoral except the land value tax (not to be confused with property taxes) and other pigovian taxes. However, I'm also a pragmatic person and therefore, it may not be possible to fund an entire government through these taxes alone as most Georgists believe. 

That is why I want to ask how much revenue would an 100% land value tax be able to generate for the Indian government, assuming no changes in the current levels of the government. 

I do realise such a tax would be difficult to practically implement due to poor land records in India but nevertheless, I'm interested to know if it is feasible in theory.
