Here, let me quote his last paragraph before the edit for you:
I may not be the target audience though as I also totally want socialized healthcare, free education extending into the collegiate level, and a UBI replacing all welfare programs, because those fall under the "General Welfare" set out by the Constitution and those things would cost less than what we have now for far better outcomes.
See that "I also totally want socialized healthcare" line?
He literally said "I totally want socialized healthcare".
But that's where socialized healthcare comes in. None of what you brought up would have to be covered by any sort of UBI. Especially since if we had a national UBI we would probably already have socialized healthcare since the latter would be easier to get through than the former.
I was at the capital protest, didn't even realize it was canceled until they started talking.
I was also at the Earth Day protest and I loved seeing way more people today. I didn't do the march and it was awesome seeing the march come down the street toward the capital grounds.
I wish we could have had their planned schedule today but I'm glad they still did something and it was a good mix of protest and the somber reality of the assassinations.
For reference see Bernie Sanders.
