> UBI is easily removed by inflation

Source? A $20k UBI wouldn’t likely secularly increase food costs on a per-calorie basis. Those folks are already eating. There will just be supply-chain friction as the system adjusts to their newly-expressable preferences.

Just my hunch, as no major country has really rolled out UBI for everyone.

For example, how about supermarkets increasing prices? We already saw that happening for a few years since the COVID. And how about landlords increasing rents?
