I like the simple argument made here about UBI enabling efficient consumption. I worry about three things with UBI though and they're more social than economic. 1. Power Divide - society will be easily divided into two groups: those who depend on the UBI to live and those who don't. The former will be absolutely at the mercy of the latter.

I have another concern. What will stop landlords from increasing the rent by high percentage of basic income? Suppliers always price their goods as high as they can for the specific values of supply, demand and competition, and none of those things will change. The customers will just have more money to pay for the right to live under a roof.
If enough houses can be built, and basic income is high enough to pay free market prices, then any landlord who asks too high a price, will price themselves out of the market because there will be other cheaper houses. But for this it's vital that the supply of houses is unrestricted.
Of course a landlord might bait and switch with low rent as you move in, and rapidly increasing rent once you get settled. That's simply something that needs to be banned. After you've moved in, landlords should only be allowed to increase rent by either inflation, or the average increase in new rent in the area. But preferably just inflation.
