I love the concept, but for $2 more you can just buy a cheap 500 level ticket and guarantee yourself a seat and still have access to all these outfield district viewing areas as well. If they are gonna offer this general admission ticket with no seat, it should be significantly cheaper or have exclusive standing room access areas for those tickets only. Why wouldn't you just buy a $22 500 level ticket instead, at least if these areas are packed you have a seat to go back to.
