It’s not that they are completely useless it’s that they cannot test the actual affects on the economy. If you have a small scale UBI even if it’s on say a scale of a whole town it’s still not enough to evaluate the economic impact because the supply/demand economy isn’t that localized. We have other experiments that have shown to have a negative effect for example rent allowance in the UK which essentially set the lower limit for rent as no one rents below what the council would pay, this has increased rent prices even in places where there was no negative change in the supply and demand.
