No thanks. The former Naughty Dog guy kept talking about this system of paying and I found myself cringing.
In the video they cut to footage of Battlefield Heroes which I would reference as why I don't want this model to grow. Especially after the December update which made it so that VP (in-game currency you earn playing the game) was even more useless for renting items and weapons compared to if somebody used BF (points you buy with real money).
