My point is that the forest laws and forest departments in India are set up to criminalise tribals whatever they do. Most of the rules date to the British era, when the government wanted to protect game animals from the tribals and farmers. So when tribals, who have been hunting boar and other common animals for thousands of years, are suddenly told that hunting for food is a crime, they have no option but to break the rules. Now they have a choice - keep hunting boar and deer every week and risk arrest each time, or kill a rhino and get enough money to last a few years. If we could relax the laws on hunting common species, I expect to see rhino poaching go down automatically. Some Indian states have more liberal hunting laws (for tribals) than others, and in those places you do see reductions in human-animal conflict.
If you don’t want to take my word for this, or would like to read more, I would suggest the last two sections of An Ecological History of India by Prof. Madhav Gadgil and Ram Guha.
