Yes, we could say that work justifies payment (very simply and roughly). But that is not in dispute. It is that it does not justify payment by a particular means -- one that restricts the freedom (to copy etc.) of others. And -- you will forgive me if I am mistaken -- I am afraid inclusion of the word 'fucking' does not quite cover that.
Does payment depend, necessarily, on restriction of copying? No, it does not. It is possible to be paid in other ways -- that do not impose on other freedoms. Then in the most general sense, that sounds like what we ought to be doing (i.e. that is moral).
Again, in so far as it turns out most practical to pay by copyright, that is how far it is justified. Not in some other ethical way.
