universal basic income is not sustainable in the same way minimum wage was not sustainable, looking as how even $15/hr isn't enough to cover rent basically anywhere where they actually pay $15/hr.

That's a bit different problem. What UBI could do is let people migrate away from very expensive places because they would no longer fear they'll become destitute if they risk not being able to get a job in cheaper place.
Minimum wage is sustainable because it is usually set based on economic reality of each country to a value that affects just a small percentage of laborers.
