As one implementation of that, a UBI can simplify the complexities of the existing safety net systems and smooth the welfare cliff.
I no longer need to pay for low income housing (I can just get some money and rent something), I'm no longer restricted by what an EBT card can buy (I just get money), I don't need to qualify for XYZ niche benefit (I just get some money), etc. And that money could more easily be adjusted/reduced as my income grows which smooths the welfare cliff.
It also frees up a ton of money that was previously used to manage the existing complex systems and allows more efficient spending.
There's enough ways to hate him without getting into shaming things he can't change.
