I think you are ignoring the fact that people have different brains. Sure, persist through mild discomfort.
But would you advise people who are hallucinating to do the same?

The stuff that comes up, including the hallucinations, are brought to the surface through your practice, but they are not caused by it. The only way to deal with them is with an experienced teacher, therapist or with self discipline (the latter i only include as seemingly this is what shakyamuni apparently did).
Everyone is different, I agree, but sitting with inexperienced people and expecting some enlightenment experience is definitely going to go wrong for you.
