The only reason I can think of would be that they don't care - you build computing structures out of all the available matter, and the energy requirements tturn out to be less than the entire stellar output. Might happen if people settle for my 'Zeus' model of megastructures (cold diamondoid planet-sized system), but I better do some calculations on how to maximize the information content/production in the entire system.

Hurray! Hmm, maybe we should as posthumans just rearrange the solar system to "improve" on astrology? :-)
