while I can appreciate the reason for not assigning zero to ordinary, finite claims about the world, such as the existence of an invisible dragon in your garage, I do not see a reason to avoid this zero.
The probability is roughly the probability of consistent combined failure of all the mental systems you can use to verify that (knowable?) actual infinities are impossible; similar to your probability that 2 + 2 = 3.
