Nonachievable

A health care plan which features a significant component of nonachievable objectives (because of the NSF-Bar or for other reasons) may possibly be of some use as a statement of a long-run "ideal" state of affairs to which the country might in some way and some day hopefully aspire.

Naturally, a minimal rewrite is a nonachievable ideal in most circumstances, as the absence of all but trivial conditions would have significant knock-on effects for other causal conditions, meaning that everything else would not be the same.

Rather than aiming for the nonachievable ideal, a realistic ambition could be to have a component model and a framework which allow for analysis of response times based on abstract models of components and their compositions.
