Not just rent either. Prices will rise across the board. The thing no one ever seems to mention when talking about wealth redistribution in purely financial terms is that there isn’t some untapped reserve of housing, groceries, transportation, or any other good that’s just waiting for more money to buy it. If we give people more money to buy these things, it might spur more production for some things that have an elastic supply, but it’s more likely to inflate prices. Billionaires don’t use their wealth (generally) to consume millions of times more bread than the average low-income person.

If you give more people money to buy things, it’s more likely to spur production than raise prices in most cases. If there’s more demand for groceries, it will probably be met with more supply rather than higher prices.

That assumes no supply-side restrictions. With housing in big cities it's often supply-side restrictions that cause the rise, like zoning.

For instance: affordable housing. If there were fewer zoning restrictions on micro-studios, housing developers might be able to pack more units in to get the same amount of profit per sq-ft. Instead zoning means that you get the most $ per sq-ft building luxury apartments.

One thing UBI has over housing vouchers is if it's not tied to location people can live where it's cheaper.
