The only alternative (to the the impossible option of wealth not depending on work or to slavery) is to admit that if people choose to do so, they do not have to work, but they will suffer the consequences.
Isn't this exactly what basic income does? If you don't work, you just get the basic income. If you work, you get the basic income plus some income from your work. (Yes there is a tax wedge so you're not going to get your full market value, and this necessarily hurts overall output/economic growth - but precisely because people vary so much in how productive they are, it's still a big win in utility terms compared to not having the BI. Not to mention that the actual real-world alternative isn't really "no BI", but redistributionist "welfare" as we know it.)
