Lookup tables get very large as the number of potentially valid outputs increases and can do only so much (no way to incorporate state with a lookup table).
(Memory elements are lookup tables with feed back. Very instructive to deconstruct for example the gate diagram of the D-flip-flop 7474 into one table with five inputs and three outputs.)
