I think that having some difficulty and having to "bloody your forehead" acts as a filter that you cared enough to put a lot of effort into it. From a consumer side, someone having spent a lot of time on something certainly isn't a guarantee that it is good, but it provides _some_ signal about the sincerity of the producer's belief in it. IMO it's not gatekeeping to only want to pay attention to things that care went into: it's just normal human behavior to avoid unreasonable asymmetries of effort.
