> What does crypto get you in most of those cases?
Speed and reduced operational costs, for one. If I wanted, I could get a collaterized loan on DeFI and have the money on my bank account faster than it would take me to fill the bank load application form.
Most importantly, it gets disintermediation: a bank might be interested in selling a loan if it has some level of profitability. In DeFI, anyone can be a bank, so the market tends to be a lot more open and competitive.
> In most of these cases, e.g. multiple properties or non-liquid assets, I'm not sure why I want to put down more collateral anyway...
Because, e.g, you've done the math and you realized that you don't want to pay more interested that is needed?

Sure: https://trustlines.network/ TL;DR: it's a system where people can create distributed credit lines, local currencies (for use in impoverished communities that have no money but still need to have a credit rating mechanism) and so on. People could do this with community banks and credit co-ops, but it would be extremely difficult to have, e.g, such a system being capitalized by someone outside of the community. With Trustlines, you can have people in rich countries contributing for the system without middlemen like in a standard micro-credit alternative.
