By this do you mean you think money is better spent by giving people food stamps, subsidized housing, and the like as opposed to simply giving someone cash?
UBI is not only more humane but also creates less overhead than the alternative of the government having to figure out not only how to allocate the funds, but how to actually distribute it to people that need it. Welfare is a complex system and there's a lot of available funding to different "targeted programs" but the burden of knowledge is placed on the people who need the assistance to seek those out. I find that burden unreasonable.
