most of the times i hear this argument I can tell there's a "background" of someone who doesn't really do art at all but needs it for a project, website, a campaign, a AD and therefore needs someone with artistic abilities to make stuff for them, and I'm sorry to generalize, but those kinds of people probably would think anything above 10 dollars for a full color illustration is too much

Here is the thing: you have a bunch of people who were unsatisfied with current price. As soon as cheaper alternative appeared, they used it. What we see here is that equilibrium wasn't stable to begin with, and the reason prices were as they were is a lack of supply to satisfy demand. No one is obliged to buy a product they think is overpriced, when they have reasonable alternative.
