I don't understand why people fixate on planets. Not only do we not need them, they're far from ideal. 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.

Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.
