Details of trading

Cynics might suggest that much of the randomness in practical markets is associated with details of trading. For much of the money actually made from markets on an ongoing basis comes from commissions on trades. And if prices quickly settled down to their final values, fewer trades would tend to be made. (Different entities would nevertheless still often need liquidity at different times.)
