This is the type of question that could only be asked by someone who doesn't care much for participating in the markets on any meaningful level. It is as if to say that one should play the markets, just don't play them well, or else you should fear that you'll be flagged for suspicious activity and punished. Imagine if this same ridiculous logic were applied to other parts of the game. Maybe you grinded one too many FATEs, and SE suspects you of experience hacking. Well, let's reset their level to 1 just to be sure. Maybe you completed your relic quest just a little too quickly. You could have glitched the bosses, so let's be safe and destroy it.
You guys saying "price your items low so that everyone can afford them!" are basically asking for the markets to function on a level that is completely backwards to what is natural. If the markets are unable to function the way that they are supposed to due to fear of being punished for performing exceptionally, then it prevents the economy from functioning as normal far more than a little inflation would, and trying to make money in this game becomes a completely boring game of "perform fairly decently and try to guess how much I can make without getting my progress reset." Maybe in a month, a crafting buddy tells me "darn! I made 12 million gil on the markets and SE reset my progress!" and I get to reply "Hah! I only made 9 million and I was safe, you shouldn't have played so well!"
