I think the arguments of UBI as a job replacement tool is misguided at best. But as a way to replace a wide swath of anti-poverty measures it could be great. By being universal it provides value and consistency that can benefit everyone.
In this I suppose I align with the older Libertarian arguments for UBI, it's one of the smallest-government safety nets you can provide. Decreasing the size of government isn't a top priority for me (and I'm not a Libertarian), but it's still a nice feature.
