An easily commoditized skill can still generate a tremendous amount of value. However, the worker is unlikely to capture most of that value. In fact, if a worker captures all of the value, there would be no benefit to the employer.
The point of the post is that we aren't in a labor bubble, because the amount of value created by a programmer is much higher than the programmer's salary. For instance, suppose that a contractor installing marble countertops on luxury houses out in the desert gets paid 100k a year. It turns out that the value of those countertops is below 100k a year. This could be used to suggest that the jobs themselves will disappear (or salaries must drop dramatically), as the value they generate isn't sufficient to justify that pay.
Now suppose installing those countertops generate 200k a year in value, but that it is relatively easy. That would suggest that salaries could drop even though there is a surplus of value in the existing salary structure. However, it wouldn't suggest that salaries need to drop because value generated isn't sufficient to justify the pay level.
I think that's the point here - that the amount of value generated is so great that programmer salaries could remain high. It doesn't necessarily mean then will, just that we aren't in a salary bubble where salaries are higher than value generated.
