I don't think you are doing this intentionally but your question is a bit of a straw man. I've never heard anyone flat out propose BI replace basic social services and safety nets. Those programs IMO would continue to exist and function but with a different set of external realities (since BI would change everything). It is hard to imagine that welfare itself would continue as there would simply be no one who qualifies but possibly it would for extreme situations. If you assume universal, single payer, healthcare then you are talking about education programs, drug addiction, etc programs continuing to exist as they do now. Anyway, what happens if you take your entire welfare check and blow it now? You turn to your family or you go on the streets. So not much would really change on that front and this isn't really relevant to BI or a flaw in it.
