There certainly is a prerequisite, but it is more of a simultaneous thing, that being that you can't point the finger without (literally) pointing your finger at the self also.
I've seen you defend money being unnecessary, to which I agree, yet you participate in and perpetuate the system and now (apparently), are saying one act of accepting money is better than the other.
There is no excuse as to why you should be able to work for money and those that do spiritual work shouldn't. There may be a higher effect, it's possible, but it is moot in the end. In essence, neither should be charging. Everything should be devoted towards serving others and therefore be considered spiritual. Everything should be freely given, because no one owns anything and your line of work is not an exception. So the point is, we acknowledge that we are in an unfortunate position and do what we have to to survive and progress. Ideally, someone doing spiritual work could lessen the impurity of directly charging for their spiritual work and support themselves with side-tasks, but that isn't always the case.
We are essentially caught in a philosophical divide here on the nature of criticism, not about the specifics of money and spirituality. I think it is more important to call attention to the character and intention of who is being criticized. I would say it is more worthwhile to make a distinction between those who seek great profit and those who are really trying to make a difference. In this way there isn't a debate about participation in different levels of a system as somehow being better than the other (spiritual vs. 'non-spiritual'), rather, we focus on the intention behind the participation as what is ultimately important. If any participation in the system is ultimately bad, then it is essentially the character/intention behind it that the distinction lies.
I question the difference of impurity however, as it relates to intention. If your intentions are good, it may offset some of the impurity, and therefore the effort could be considered worthwhile. We can't know the specifics on a metaphysical level. It is best to work towards purity as you say.
