That isn't a counterargument. Regardless of whether or not you think someone's writing is good, to your taste, or nuanced, there's still considerable (and, I think, reasonably rare) skill involved in making something that the general public wants to pluck off of the paperback shelves (or e-reader equivalent). It might be tawdry, silly, and factually inaccurate, but those qualities are orthogonal to whether or not you can write a story that people want to buy.

Is there? The general public can be sold any kind of crap that takes minimal effort -- and in the same way, don't buy masterpieces that take tremendous effort and skill to create.

This isn't an argument on actual writing skill though.
It's like you measure a new category like "skill of writing best-selling stuff" that's not necessarily connected to the skill of writing itself -- just to the degree of sales.
But one can sell bad stuff or skilless stuff too. Sales don't show anything more than a skill in sales themselves.
