Sure, I'd assume an author wants to sell as opposed to NOT wanting to sell, but anyone writing a novel in present tense would be aware that it would not be likely to be a commercial product. It would be more of an artistic endeavor.
Just as we have "art films" which are sometimes rather difficult and not too accessible, and Hollywood blockbusters, which are the opposite.
Chances are pretty high that someone writing in a way which strongly challenges the reader or puts the reader off balance is more interested in following a certain artistic vision than in making a potload of money. If that vision doesn't speak to you, you're certainly within your rights not to like it, or to consider it a failure. Not all art is good art, and not even all good art is meaningful or worthwhile to everybody.
