In Options/permissions, do not offer the role menu for "...can comment on this card" (maybe not worth doing with existing permissions system, but certainly with new one)
Regardless of comment permissions (which could be set before changing cardtype to Pointer), do not show the comment interface on Pointers.
disallow commenting on Pointers

I'm guessing we only want comments on Basic cards and simple custom cardtypes, no?
