Yes, and this is the biggest problem i see with the plan for a resource based economy.
Peoples dreams and wishes do not match the needs of a society.

This is already a problem, despite there being control mechanisms in place to direct people towards certain functions.
I mean, what is the societal benifit of researching the mating behaviour of some ecologicly unimportant insect?
And yet there are many biologists doing exactly that.
And not only biologists, but scientists in general do a lot of work that has no direct benefit to society.

Now imagine everyone doing only what they want to do.
How would societies needs get fullfilled then?

What would propably happen is that an elite of worried and responsible people would rise to control the circus.
They will become more and more separated, maybe even becoming a slightly different species due to different evolutionary constraints.
Humanity would effectively be creating an overlord class which we will have no control over.
And we all know what the chances of an overlord class being benign are...
