so, basically, according to your example, we could take yearly welfare spending, assuming it’s 1 trillion. Every year, delete an entire section of bureacratic bullshit, and then everyone would get 5 grand annually.

If you remove every welfare program that exists, sure. But that’s not good–remember that UBI goes to everyone, while welfare program dollars go based on need. So it stands to reason that the average person who gets some sort(s) of welfare now, will end up able to buy less care with that $5000 annually, than they’re getting now.
