The cost for "doing something now" will be high - in more ways than one.
Very true. And this is well understood. But the cost of dicking around with a intractable, unwilling GOP, would be higher. All the GOP seems interested in, is killing time until they can make it to their next "vacation". It has been like a relay-race. They come to D.C., waste time, waste time, delay, postpone, waste more time, and then 'Alright!', they make it to the next vacation...
They're just hopping from one vacation to the next. It must be greatest job in the world. I don't know of anyone in civilian/commercial life who could function like that. You would be fired or go bankrupt in no time. But, government work is a different world from reality. So, what can you do?
