Can ObamaCare reduce spending?

So, to beat a dead horse (with facts!), I'll briefly respond to those who say ObamaCare costs too much to implement. My response runs like this: the non-partisan Congressional Budget Office (CBO) published a study in July 2012, which evaluated the effect of John Boehner's proposal to repeal ObamaCare. This piece is sourced multiple times in the wikipedia ACA article. So, the CBO found that REPEALING

1. would "increase other direct spending in the next decade by an estimated $711 billion."

2. would "reduce revenues by an estimated $569 billion over the 2013–2022 period."

I'm no math genius, but that looks like repealing the ACA would INCREASE deficits. 

Overall, here's what the CBO finds about Boehner's 2012 plan to REPEAL the ACA:

On balance, the direct spending and revenue effects of enacting that legislation would cause a net increase in federal budget deficits of $109 billion over the 2013–2022 period.

This is what the current shutdown is all about. Republicans want to repeal ObamaCare because it....errr....helps poor people....wait, err.....is vaguely French....or, errr it costs too much. In fact, not only is the ACA based on conservative principles (RomneyCare, anyone?), but it REDUCES the deficit and helps provide health insurance to millions of the sick and poor. How do any clear-thinking individuals oppose this without providing a superior solution? I would really love to learn what I'm missing here.
