Why not, if all else fails, do a run of the completed matter to see what
the pagination would be, then do something like:

\newif\ifhidden

% Uncomment this if you want to hide content.
% \hiddentrue

\ifhidden
 % . . . preferrably use ConTeXt-friendly pagination
 % commands; this was taken from a plain old TeX file.
 % Shove in white space or \phantom{} boxes with dummy text of
 % equivalent length; ConTeXt likes its own \blank{} macro.
 % Raw TeX stuff can mess up pagination and spacing.
 %
 % I'm not sure if a \vbox to <dimen> {} works well or not here.
 % Just try a few ways to see.
\else
 % Put all your usual content here.
\fi

It's a kludge, but it should work in a pinch.
