Even now they’re rationalizing - US banks offer 0% interest and took $12B in overdraft! See how much worse that is? Well except the $12B is out of $18T in assets so DeFi hacks cost 1400X as much per user.
In fact 10% of all TVL in DeFi was stolen this year. That means if you’re not making a 7% return for inflation and a 10% return for risk loss, you’re losing money in real risk adjusted dollar terms invested in DeFi. 17% APR in DeFi is equal to 0% in real dollar terms.
