> Anything can be collateralized, including things that don’t have stable value
The article doesn't mention collateralization so I don't see your point. There is collateral in that the person is using a loan to buy a valuable item, so that item is used as collateral.
> There’s no scenario where some dude off the boat from Pakistan or Haiti without assets should be able to borrow $1M for the right to drive a single cab. This story makes the exploitive and scummy Uber/Lyft business model seem ok in comparison.
Do you suggest limiting loans to only dudes that aren't "off the boat"? Again, it's not in the banks interest to lend to these borrowers if they have no intention of paying it back or at an asset value that will fall.
It's unfortunate that there is artificial scarcity for these medallions that resulted absurd market values. But most businesses require some sort of financing. Few business owners have liquid capital they can use to get their business up and running. This is especially true for many entrepreneurial immigrants coming to this country.
