When I use the sink now, the water ends up right where it started, and the next town downstream can use it too. If I watered plants and didn't let the water return to the river, the next town downstream wouldn't be able to do the same thing. For them, it's objectively better for me to send it back to the river than give it to the atmosphere via plants.
