Admittedly, I am not familiar with maker I will have to go take a look.

I guess the difference between me and someone who would use these DeFi apps, is that they are using crypto as a speculative investment (which is fine, I speculate with other assets all the time). But most people do not have a significant portion of their net worth in crypto tokens. For me, it is much cheaper/easier/safer to just get a traditional loan.
