Another reason why digital comics suck

I'm speaking mostly of the Big 2 publishers, and higher tier ones. Another reason why digital comics at full cover price is unthinkable is that the publisher is not distributing these books through Diamond and eventually through the retailers. The basic idea behind retail sales is that the retailer pays a certain amount that is less than the selling(cover) price. By selling the comic at the cover price, the retailer makes a small profit. The cost that the retailers pay for all of the orders and preorders needs to cover the cost that the publishers pay to produce and print the comic. When the publisher doesn't need to print the comics, it costs less to produce them, and when they don't need to sell the comics to a distributor that, in turn, needs to sell the comics to a retailer, it costs even less than less to get the content to the consumer. To charge more than you charge the distributor for product that you can provide directly to the consumer, is milking us for more money.
My point is, publishers make more money by providing digital content to consumers by charging full cover price. So why not be satisfied with making the same amount of money by spending less to get that content to the consumer and pass that savings onto them? Because they are greedy bastards that think that we can't figure out this simple derivative.
I will continue to buy my comics at a retailer and enjoy owning a physical product until digital content can be made worth my while. I don't mind waiting.
