Misrepresentation of the mandate in the Supreme Court: why it still matters

I have made the case below piecemeal, across many posts. This is an attempt to make it as succinctly and completely as possible.

In his oral argument against the constitutionality of the ACA's individual mandate on March 27, plaintiff's counsel Michael Carvin asserted, "Congress prohibits anyone over 30 from buying any kind of catastrophic health insurance" (p. 105).

That is not true -- the ACA provides the catastrophic coverage option for others exempt from the mandate, e.g. on grounds of financial hardship. And that factual error signals a greater distortion, one that was not countered and apparently made a major impression on Justices Alito, Roberts and Scalia: that the mandate forces Americans to buy coverage greatly in excess of what's required to offset the cost of catastrophic care for those lacking health insurance. No one pointed out that a) the ACA provides a catastrophic coverage option for those under 30; b) that it extends that option to others exempt from the mandate on financial or other grounds; or c) that the bronze plans offered in the exchanges, as the Kaiser Family Foundation recently detailed, might also reasonably be labeled "catastrophic" coverage.

It seems to me that a) the justices were misled on this potentially crucial point, and b) Kennedy and/or another might still be convinced, if not to accept the mandate as constructed, to divide the baby by further limiting it -- as Marty Lederman suggested they might:
