"In fact studies have shown that free copying makes near zero impact on DRM infected purchases."
First of all DRMed purchases are only a subset of paid-for or what would have been paid-for creative output.
Secondly, "studies have shown" means a study has argued. I don't agree with every argument I hear. Do you? Perhaps you'd give a citation and tell us which bit you support. Because it seems to me trite economics, virtually beneath saying, that providing something for free destroys the market for it.
You also say there is "zero evidence that [advertising] is at the expense of purchases via the copyright cartels" - which seems to me incorrect, utterly, because the advertising money helps fund and incentivise the locker which destroys the market for goods. And in any case it's a form of profiting from theft.
Finally, you write that there is "zero evidence"; yet as I say, not only is it trite economics, as I mentioned above, but also in part counterfactual, owing not least to the incommensurability of today's market with one un-wrecked by digital copyright theft of 18 years ago - but counterfactual or not we can still make arguments and dismiss others. Methodologically, "zero evidence" claims seem to me deeply iffy in this case - you just mean you don't have any, which given how little you've thought about in a rounded way seems unsurprising.
