I think you are a little confused on the " makeup " of dance in general.
Social does not necessarily imply that one cannot use it for Comp entries. On the contrary, most amer.style comps have their largest entries from the lower divisions.
As to technique.. you are correct that it IS necessary to apply this to all that you dance, at every and any level.. WHEN it is taught in depth , is a moot point.. much depends on how frequently one takes lessons and practices on a regular basis..learning basic structure, like direction, rhythms, and amalgamations in addition , developing your poise, posture and frame .. all are fundamental to your learning process, and one cannot apply technique, if you are unable to dance without first mastering basic concepts..
Every comp. dancer went thru the same process.. basics.. basics and more basics..
You have the normal frustration of all beginners.. remember,, dance is a marathon.. NOT a sprint..
