I'm up in the air for this one, but FR banking also helps accelerate capital creation. If I give a new business $100 of fiat money and they create $1000 worth of goods out of it, paying back $110, that's helping make everyone wealthier, the original depositer included (if not interest, then free use of a bank.) This is only good to a degree because every fiat dollar given out is a liability and risk. I think FR banking could exist in an open market. I also definitely think the whole banking industry in the US is intensely corrupte, skewed, and cartellized (sp?).
