first, its only been a few hours and you already have way to much to say about how this will affect the economy. The update is intended to stop bots, which it should, and to increase the amount of people selling their own creations, as in rc'ing and selling their runes. Runescape is about skills, and so they are encouraging people to actually raise their runecrafting level so they can make their own fires and cosmics and laws and deahts, and now their own blood runes. Its no suprize to me that this came out weeks after the zmi alter did.
