So what number were you using for the "raw material in the solar system?"
And what manufacturing technology? Avogadro's Number is 6.02x10^23, a mole
of carbon is only 12g. Using electron spin to store a bit as is being done
today in quantum computers requires only 12.5 billon tons of carbon to
store all of this information. That wouldn't even use up all of Mercury,
much less the solar system.
