There is a perfectly good reason why "the entire process shouldn't be monetized". It's a super big fucking distraction to have people at your recording studio when you're trying to do something that is already extremely difficult. The entire process IS monetized, because you're supposed to pay for the copy of the work you take when it's over.
And for the record, many artists do take songs on the road, try them out, and change them based on public reaction. Then, they come home, spend money and record it. You want a copy? Pay for it.
