Not a very good article. It doesn’t even discuss or provide reference to Virginia that has some of the best protections around. Why? Because our right to self defense in VA is not codified. It’s all common law.
As for statutory protection, TX probably has the best. there is some right to protect property in TX with deadly force. But it’s still a bad idea. In my view deadly force is to be used to protect life and liberty, hard stop.
Here in GA we have Castle Doctrine and Stand Your Ground. You can basically shoot somebody out in your driveway if you feel threatened. Personally I would only do it if they broke in the house.
