The first point in the martial arts says you can use STR or DEX for attack and damage.
The second point lets you substitute the unarmed attack die if it helps you (I don't think this is controversial, doing versatile damage until level 11, at which point unarmed does the same -- you can have a stick or not; the stick only does d10 at level 17).
The third lets you make an unarmed strike as a a bonus action.
