Why do you think that it would be impossible to make a society where

a) everyone gets to live like a king, unconditionally, from birth to death, and

b) people have the freedom to do and pursue what they want?

I don't see "some % of the population becoming lazy couch-living larvae" as a problem, because if they truly are "destined" to become that due to their inherent brain formation or whatever, then they were always going to do that no matter what (or drift off homeless in the streets in today's society). The only reason that's a bad thing is that society would then be missing a person who, in different circumstances, would be contributing with labor. But since in this hypothetical future utopia human labor is no longer needed, and that % of people were always going to be lazy or whatever, then there's no loss to be had by simply letting them be!
