User blog comment:Interdimensional403/Inter universal travel does not mean unlimited resources/@comment-1743498-20130608210348

I don't follow the argument you are trying to make here. I understand that definitely not all universes are habitable. However, if one possesses the technology to go to another universe, there is a good chance you'll be able to travel to exactly the one you want to avoid the numerous problems associated with it.

This was the reasoning that led to the conclusion that it could lead to unlimited resources:

According to the many-worlds theory, there are an infinite amount of outcomes. That is, a universe can be as different as having a displaced atom to an entirely different chain of events starting from the beginning of the universe.

So essentially, if you have an interuniversal drive, theoretically, you could pick the exact universe that suits you. Say that you just mined out a planet for all of its resources. Using an interuniversal drive, you could go to another universe where that planet is not mined out yet, and mine it out again. And it's rinse and repeat from there.

You could also do things such as replicate objects, or more accurately, taking them from another universe. So long as you have the energy to be able to create the portal to the other universe, you could get as many of this object as you want. The energy requirements should not be a significant problem either, because those with this technology aren't limited by the energy just found in their native universe alone. Infinite universes would technically mean infinite ways to get energy.

Basically, the bottom line is that with the ability to go to a place that exactly suits your needs, it's a power comparable to a deity. That's why we've limited the extent to which a civilization can tamper with the space-time continuum. It would make for some great future stories either set in the distant past or distant future, but it's out of place for a story set in the present time.
