Why do I need to get congress? Congress isn't some magical body that is somehow more responsive or well run than the executive. They have more special interests. Why would I want a delegate from some state have a say that the government should have less of a reach into my life? That just means id have to essentially bribe this person with some special carve out for his state which is how we got into this whole mess. Lot simpler to just have more or less a national referendum for delete power
