Well, maybe it's a little like that. Thoreau lived in a time of bad economics, depressions, recessions. Though finally his family business took off, he spent most of his life freaked out about money. (Emerson was even more freaked out, but Emerson would not have watched the Super Bowl, whereas Thoreau would have. This I believe.) Thoreau needed the dough to write. I don't know much about Dylan's current cash situation. Maybe he needs the dough too.
