They have their place and I doubt they're going anywhere. As mentioned they are intended to be mostly sedentary and not drug around like an RV. The exceptionally tiny ones are not at all attractive to me, but the larger ones do have their charm. They should be treated like mobile or modular homes by the local governments. Especially if they're built to those "sticks & bricks" standards that make them difficult to tow. Non-issue there. I could envision scenarios that we as empty nesters might enjoy one seasonally.
