If someone wants to live without the benefit of a whole lot of things which are really really nice to have, like plumbing, then they have my blessing.

But even if that is your desire, then a dome is a ridiculous way to achieve it, compared to a rectangular structure with a pitched roof, which is easier to build, more stable, is less likely to leak, will probably last longer, and gives you more efficient use of space and materials. Domes solve nothing.
