It's too early to judge a new economy system one day after its release. I didn't have much time to play last night, but I got a bit of time in, and already have started collecting the new infusion currency through regular gameplay. You've also conveniently left out the detail that the two noted expensive materials are directly offered through nightfalls. Direct conversion from cores to higher-end currency is not the primary means of obtaining these items. Please don't misinform people.
