I think this is a critical problem to solve with UBI. If you give people in expensive areas more money, more people might crowd into cities, intensifying the affordability crises in places like SF and NYC. Plus there are strong incentives to cheat the system and lie about your address, or even to live homeless in the most expensive cities to collect the higher UBI payments, etc. So ideally we'd avoid this and everyone would get the same amount of money. But, if we continue to let city prices shoot up, we might end up in a place where people want a job but can't get one because they live somewhere cheap and can't afford to move to the city where all the jobs are on their smaller basic income payment. With or without basic income, we're clearly on an unsustainable path of letting cities get so much more expensive so quickly.
