There are no "pluses of the GOP plan" except one ... it will be a failure. And that is a plus only for the GOP (right wingers) by demonstrating that the government is incapable of providing healthcare or anything else resembling a social program. Right wingers love to see the government fail in these types of endeavors so they can promote the "free market" (AKA, their wealthy benefactors and large corporate patrons). They don't want the government involved in anything including waging war (mercenaries vs national military) and the criminal justice system (private police forces and corporate owned penal institutions vs public law enforcement and penitentiaries).
They want government restricted only to making laws that favor them and their moneyed interests.
