Thats actually not true. Some of the best authors wrote their works while in the situation, not isolated in a cabin. Einstein completed his greatest works while working as a patent clerk. The idea that you just need to get out into isolation and you'll make something great is a famous wanna-be author fallacy. In fact, if you read much literature related to the creation of novels, they debunk this idea repeatedly.
Being isolated can help you focus, but if you really have the drive and that perfect idea, it won't matter if you're alone or in a crowd, you'll be focused on it.
