It will take significant resources (probably more electricity than can be generated by all fossil fuels on Earth) and time (orders of magnitude greater than the age of the universe) to generate a complete Bitcoin address "rainbow table".

If you don't understand the math in the key pair generation you should take that as an indicator of the uncertain ground on which you tread.
