Can the 'tiny house movement' last?

An interesting short piece by Emily Folk in The Ecologist poses exactly this question. Here's a snippet from her conclusion:
Until more people choose small homes and they become more mainstream, their legal status will likely remain foggy. Without concrete legal status, the future of the tiny home movement will always be a bit uncertain. However, that legal status is one of the biggest reasons the tiny house market is as small as it is, making this a challenging problem to solve for small house lovers. Will the tiny house movement stick around? Only time will tell. It's especially hard to say because it is such new, unexplored territory. The movement does face some significant challenges, though. For the tiny house trend to become sustainable, it will need changes to laws and a substantial shift in the way we as a society think about what it means to have a home.
