I disagree extremely hard.
The monk should not be so focused on unarmed combat. The brawler should be a fighter or Barbarian, heck there’s even thematic space for a rogue, but none of those are the expert in a mystical martial tradition that seeks to take the study of a particular martial form/system into a transcendent Art.
The monk's distinctive feature is unarmed combat and unarmored defenses. It says so right in the class description. That is what the monk should be doing. Aside from the Beast barbarian, every other martial uses weapons and armor.
