Except few engage in this sort of work. If left to their own devices, most people would simply consume content produced by the 10-20% of people who would actually do anything useful.

This is my observation. People are so weirded out when I tell them all the stuff I want to do. Most people just laze if left to their own devices and provided food. People have this image of hunter gatherer tribes doing interesting things in their free time, but the data show that, unless they're hunting, gathering, cooking, or doing other biological imperatives, most of their time is spent lazing.

That's fine, but if your argument about not working is that humans are going to engage in 'dream work'... well I think that's just silly.

Ultimately, from what I've seen, people with this mentality, often end up becoming quite well off. Those who want to engage in 'dream work' often have the self-motivating spirit that almost inevitably leads to material success.
