Yes, couldn't this really go 'round in a circle?
Say you have an unexpected prize of money that comes in, something you intended purely "for the highest good of all", "in a healthy and positive way"....you didn't "earn it" by working a job, selling something on ebay or in any other way that you have conceptually connected with "earning" it as you described.
So you use it not only to further your own trek towards financial independence but also to help others in a meaningful way.....well, can you "earn" money after it comes your way?
I say YEAH !!! And in some belief systems, that's called karma and in others that's called tithing and so on.
