The problem with current building standards is straight, flat walls.
The other problem with current building standards is that this is the same way we have been building since time out of mind. The reason we have built this way in the past is that we were not technically nor mechanically nor mentally adept enough to build anything other than in straight lines. Or if we did produce something with a correct curve- it took a monstrous amount of difficulty in all three arenas. Today we have evolved past the technological and mechanical barrier.
Regardless, now we build this way because companies have built up entire industrial sectors surrounding the flat wall design. The problem with changing that comes down to a.laziness and b.complacency. "But that's the way we always done things by gum!" This standard building industry pr machine has attacked (sometimes ferociously) any other design- especially dome-styles- in an attempt to maintain the status quo. I have personally visited the dome home in Florida referenced by the OP. There was still debris scattered around at the time from Hurricane Ivan but the Dome was literally unscathed.
Not only that- but it is beautiful - story and pictures here:

This home literally cost less to build than any of it's recently built neighbors- all of which were devastated by the hurricanes.
The problem comes down to this; before we can change our ways, we need to
change our minds. The building industry could stop keeping people hostage to literally ancient building design and develop an entirely new sector in materials, design, acoutrements, etc and open up new manufacturing model of everything from plumbing to furniture.
