Hypothetically, if you shill a 1/1 to yourself on ebay, then turn around 2 weeks later and sell it for real, people are probably going to think that what you shilled it for is the correct price that card should go for, so they might bid and think it is a fair price, that is setting the market, it still is unethical, but that doesnt change the fact that its setting the market. This is the same in this case simply with a higher print run.
