Obamacare could just be ignored

Obamacare is quickly becoming the largest government boondoggle evah! I don't really think the federal government can handle something as large and complex as what Obamacare has created. Now, the administration has a challenge from courts, and states aren't all on board.

If, as the link above calls for, states simply don't implement Obamacare, does the federal government have the money, expertise and power to come in and set it up themselves? It doesn't seem so.
