I don't think you are grasping Hitchen's argument. You are semi correct in that Hitchen's used his argument in the discussion of Atheism and Creationism. But the underlying logic of his argument is the same logic that pretty much every countries legal system is based upon. Innocent until proven guilty.
Your example doesn't even make sense in the context of hitchen's logical argument. A correct use of your example would go like this. Doctor 1 subscribes to the standard system in place, that to save a patient from a brain tumor you remove the tumor, and remove as little of the brain as possible or none at all. This method has empirical data backing it up, and has been used and performed many times. Doctor 2 (You) comes in and says "Doctor 1, you are totally wrong, completely remove the brain to save the patient. I have no evidence that my method is correct but I believe it to be correct".
The point of hitchen's argument is the same as the legal system. The Defendant doesn't need to prove his innocence. The prosecution must prove his guilt.
The second part of hitchen's argument is that Doctor 1 doesn't even need to respond to doctor 2's argument because 1) it has no evidence to back it up 2) Doctor 1 doesn't need to defend anything, because doctor 2 is the person trying to change the established system. The burden of proof lies with Doctor 2, or the prosecution, to prove that they are correct. Not the other way around. This is why it is known as "Innocent until proven guilty"
So again, to use this logic, YOU must prove that the system is broken. YOU are the prosecution.
Now, this thread has become a corporation dialog between two old enemies. And it is pointless for me to continue this argument so, I'm done arguing. Dev's I leave this matter in your capable hands. I would just like to stress that before you change a working system. Make sure the system actually needs to be changed. Adding tedium to a game like this will drastically affect travel time (one of the worst aspects of this game), especially when there are systems in place already that restrict this system from being abused. Not to mention that the system itself is open to all to use. By adding in cool-downs and other restrictions like it, you will be arbitrarily restricting peoples ability to play your game.
