My rebuttal to the suggestion smart contracts somehow change everything is that smart contracts can't do due diligence on ability to repay in future, and only the sort of sucker that thinks Nexo looks like a legitimate operation would consider due diligence an unnecessary overhead to lending. Smart contracts can't make lending below the cost of capital a sustainable business model either. And whilst not all crypto is a Ponzi, 'yield farming' involving people being rewarded for propping up the value of a token by paying into its smart contract by printing even more of that token is pretty much the definition of a Ponzi. Even someone as heavily invested in smart contracts as Buterin acknowledges as much.
