It's true, totemists have to wait for level 2. Psychic warriors get it from level 1, but only for a few hours per day.
My point of view is that when evaluating this as a low-level ability, flurry of blows, being limited to unarmed strikes and selected weapons with not-very-good stats, is comparable to natural attacks.
(also psst the kobold can use a class with sneak attack, pass it on)
I'm comparing it to Two-Weapon Fighting, and the normal monk ability, which are both the standard options for multiple attacks at 1st level, rather than using circumstantial pseudo-magic systems subject to DM approval.
