I have two takes on this.
The first is: I've met people who don't work. They're some of the most boring and wasteful people I've ever met.
Lying down on a beach, or watching tv 12 hours a day (random cliches), get boring after some time.
So one's going to look for something more meaningful and committed (in best case...), which brings to the second point: anything that's going to take a consistent share of one's like, inevitably becomes "work".
Morale of the story: there is no freedom from work. But there's the option to pursue the work one likes :)
