It is very interesting what you show us here, it is an alternative that I had not studied, and that I have not heard from anyone else either. But what about the moral hazard?
Maybe I'll take a look, but more with the intention of receiving a loan, mainly because I do not have much. lol
Definitely do your research from a skeptical perspective. Nothing is a magical fix and there will almost always be hard lessons to learn. Make sure you take the time to educate yourself before making any decisions.
