For exactly the same reason that doesn't happen when landing an airplane, it's not efficient, it's complex, it's error prone. Parachutes means you have a recovery zone not a precision landing. Efficiency is all about operational efficiency, and fuel is the cheapest thing in the whole system. Burning a little fuel so that you can have a fully powered, highly controlled, high precision landing means that you are able to recover tens of millions of dollars of spacecraft reliably, and that's far more important than saving a few dollars in fuel. Precisely the same reason why airplanes do powered landings even though they have wings and it would be far, far easier for them to coast to a landing without using parachutes or whatnot. As for wind, the rocket isn't going to be launched if there's a risk of high wind gusts regardless, and most anything else the vehicle is capable of compensating for with its thrust and fins.
