Is 'repeal and delay' the best strategy for replacing Obamacare?

"Repeal and delay-" getting rid of Obamacare with certain provisions remaining int effect until some future date, when replacement legislation is ready- seems to be the approach favored by Republican leaders. But not all conservative thinkers favor that approach.

The alternative is to repeal individual provisions of Obamacare while simultaneously replacing them with provisions which keep their virtues while fixing what's broken in them.  The result would be a minimum of confusion and chaos and a steady and systematic progress toward a system involving less coercion and more reliance on the private sector. Otherwise the problems faced by those who can afford neither health insurance nor the penalties for not having it might end up being multiplied and extended to entirely new classes of consumers.
