I didn't include it because I didn't feel a need to address it. Since you want me to, here's a brief explanation. The nominal value (i.e. how many coins it's worth) of the partyhats may fall, but their real value (i.e. that they are worth more than other items in the game) will only increase, since supply is ever dwindling. Making money will always be faster now than it was three years ago. Even if coins are "nerfed" and you only get 1 coin for every 100 coins you used to (e.g. a nature rune is 3 coins, an Armadyl godsword is one million coins) - which would cause "average" income rates to drop from 500k/hour to 5k an hour - the true value created (in terms of potential xp or whatever) will be far higher because we have new items that multiply our productivity. This is called capital. New teleports, better weapons, better armor, better prayers, better potions, familiars, and still others greatly improve what one hour of playing yields. If a purple partyhat drops to 10 million coins, I will guarantee you that your Armadyl Godsword will be less than 3 million, your Bandos chestplate will be less than 500k, etc. For more reading on this subject: http://en.wikipedia.org/wiki/Real_versus_nominal_value_%28economics%29
