If I recall, WoR: Dust just hints at the people of Remnant having no idea what effect their use of Dust will have on Remnant, not that it's going to run out.

Also, I just realized why Cinder waited until the dance to infiltrate the CCT. The CCT is Beacon tower, which is where Ozpin's office is, but Ozpin was at the dance, so it was a lot safer for her to infiltrate the CCT since Ozpin wasn't there.
