Sorry Lela but you keep tossing out unconstutional as if you know what makes something unconstutional. Obviously you don't, for it takes more than your posting; it requires a decision by SCOUTUS.  By being  big and complicated the ACA is not more complicated by many things Congress passes.   
Do you believe whatever is put out for a replacement will not be big and complicated?  No it has to be when you are establishing a health care insurance program for over 250,000,000 million citizens of all ages with different medical historiesand needs. It not like deciding 'do you want fries with that."
