There is a flaw in this argument. The flaw is that the mathematical odds you and pt quote inherently assume that the options writer has no edge. The mathematics says that if the writer keeps writing forever, then at some point, and assuming he does not have an edge, he will blow up. Very true, but I believe Soc is saying that he does have the necessary 'edge' to avoid a blowout. And, whilst he continues to be profitable, no-one can truthfully claim that he does not have this 'edge'. The trading zephyr is with him, so to speak.
With respect sir I think the flaw is in your argument for two reasons:-
1. The argument is not about the Writer as a person with skill or edge, it is about Writing itself.
2. There is no evidence in this thread of 'blow-out avoidance', which is where the real skill lies.
You can Write options to your hearts content and pick up the premiums. You are picking up time-bombs for a wage, or what appears to be a wage because the job has only just started and you got paid something in advance.
It is how you perform bomb-disposal that is where the skill lies. You can pass it to someone else at a cost (buy it back) or it may fizzle out by expiry, or it may go off.
If you are still holding it when it is about to go off, then unless you can predict the change in the market in advance then you will be left holding it when it goes off. You then have to do your best to limit the damage if the market allows, and it might not; that is the risk.
And you may yet see an example of succesful explosion-avoidance here, but that does not mean that it works every time, or that you yourself can do it.
And if you believe that anyone has the skill just because they say so without evidence, then one can only assume that you are hearing what you what to hear and denying what you don't.
It only takes one bomb to go off in the right way and you are toast.
