It's crazy to me there aren't banks with 100% reserve ratio fully insured for a nominal fee of 0.4% or whatever (gold/silver storage with full insurance is ~0.4% so this probably isn't far off).

I'd much rather lose 0.4% of my money than lend it out at +0.01% to whatever checking accounts pay nowadays while they lend out to some asshole that does business with the bank.
