There are enough raw materials in the asteroid belt to build rotating space habitats with a cumulative area of > 1000 Earths. You get exactly the amount of gravity you want, limitless solar power and you don't need to expend an enormous amount of energy to to escape a gravity well if you want to travel somewhere else. All your resources come from asteroids.
That's our future in space. There won't be any need to leave the solar system.
Our need find a habital planet comes from our need to get out of the house once in a while. It's all about feeling free.
Also, we will need to leave our solar system when our sun goes nova again.
