While I generally agree with the overall sentiment and like the idea of UBI, saying we're the only species that pays to exist doesn't seem right. We're the only one that uses money, so of course we're the only species that has would pay money to exist. However, other species all over the world, many right outside our doorsteps, live much harder lives than we do and pay with their lives if they make a mistake. If I had to choose between working a job and being out in the great outdoors having to farm/hunt/craft and such to survive, I'd choose having a job, which is a choice we all pretty much make anyways. At any point I could quit my job, walk out the door, and live with just the clothes on my back... and I would probably not be able to hack it. It's not much of a choice and it's pretty much coercion, but the choice is there.
