How can they? There is no way to know what a certain knob will do N-levels down the line. They're essentially "playing" against the collective brain and will power of millions of smart and motivated individuals, and all the money behind the huge corporations that play in that space, so how can they. It's impossible and a losing battle.
Look at incentives you have created in the impacted industries, and think about what the new optimal strategy is from a cost/profit perspective. That is what behavior will converge to, and is a central concern for any good policy maker.
