Largeness isn't sufficient, but it is certainly necessary. By largeness I mostly mean a state space which is effectively inexhaustable. Humans are finite, but human state has ever recurred. I don't think the sticks and stone argument works. It sounds like you are saying something like "well we can imagine in principle performing a computation just like brains do with sticks and stones but you dont think the sticks and stones are conscious do you?" But yes of course it would have to be conscious, that's what equivalent means. Otherwise you are saying you left something out, or that brains are special computers.
