... You literally just Google "read ___ free"
It takes more effort to try to buy these Korean coins than it is to pirate the comics.
So to your effect, there are those willing to "waste time searching for free copies" and those wiling to spend time figuring out how to purchase comics (whether Korean or not). It's two demographics that will always exist: paying and non-paying. I see what you're saying, if piracy didn't exist (less readily accessible), there would be more paying readers. But that's an impossible world. We live in a digital age, a free information age.
Just like giant supermarkets have loss and theft built into their models and financial plans, so do all other channels of media (music, movies, comics, etc). You establish sales knowing full well that there's inevitably gonna be some illegal distribution. You don't dwell on the sales that didn't happen. You dwell on the ones that did happen and still have potential. Technically speaking, companies wouldn't even like the fact that libraries have manga (my town library actually has an entire room devoted to it that stays fairly updated) or if I bought manga and then just started an informal sharing group on university campus. Because all of that is "hindering additional sales."
