I honestly don't understand your comment, so let me try and recapitulate what I think you're saying and what I think I was saying, and then you can tell me where I missed the mark.

What I hear you saying is that the original comment simply said that leadership by itself is enough to preserve the Costco ethos. It didn't say anything about size or Wall Street or anything else. Is that right?

The reason I responded the way that I did is that the claim that something by itself is enough has to explain why most companies are able to be destroyed, even though they have really good leadership. I think the common answer when people ask about Costco is that the reason why, for them, leadership was enough when it hasn't been for other people, is something like they're so large. Does that make sense?

Either way, in order to say that leadership by itself is sufficient, we have to figure out why Costco has been able to endure as a gigantic public company when, for most companies, the larger they become, the more valuable they become as a target. Meaning that Wall Street or other financial forces will intervene to change their values.

And the answer, which I lay out in the book (not in my original comment), is that Costco is protected by a very distinctive thing I call a "governance fortress." This fortress (and not merely their leadership) is the reason why they have been able to endure for forty years.

In fact, the predecessor company of Costco, spiritually speaking, was a company called FedMart that had the leadership and ethos but did not have the fortress. I'll leave it to you to read to find out what happened to them.
