Quite simply; people on an individual basis can still think "meh, I don't feel like doing it". On the other hand you have people who enjoy doing such work - yes, they exist - and they are likely to either go "well I'm not getting paid for it", or they are getting paid for it but are assigned to doing it elsewhere. The general perception of "work" in a society greatly influences how productive people are. I can't even count the amount of times I've been told that I "don't do work" because I don't have a job with an employer, even though my working week is significantly longer than a regular one. Until that perception changes, people will keep being stuck with treating work this way.
