I think the advantage is in prolonged camping situations. If I was staying somewhere for a few weeks or months this would be a great, inexpensive shelter. If I am crashing for a weekend & if hiking/walking in to a wilderness site or someplace that only affords a small footprint. If you have a vehicle say with a roofrack & are driving It could work in plenty of situations. Even a small sedan/wagon/minivan could transport with some tie downs & loaded by 1 person (2 is better) They take up a decent footprint but not much more than a family sized tent & depending on how proficient you get with assembly they can erect in just as much time. I think that they would make great temporary dwellings if building a traditional material longterm cabin/house/micro dwelling in like a homestead situation. They arent quite a micro dwelling as to being able to withstand prolonged varying weather & seasons but a good temporary shelter till you build one.
I am surprised that they haven't caught on in Slab city yet or elsewhere people live for a few months at a time. Hell it would be cool to rent like a KOA campground site & build a home for 1-6 months in expensive rental markets. Utilize the 110 volt power for home style lighting, kitchen appliances & electronics (TV, wifi, cable etc). There are plenty of websites & techy type nerds who are really into the geometric possibilities of hexayurts with free plans & tips for would be builders.

My pros
1> reusable
2> can stand up inside
3> offers lots of privacy from outdoor noise/light (unless others are camping inside)
4> fairly inexpensive for a multi season shelter
5> they reflect lots of heat from the sun & or remain cooled or heated depending on if equipped with heat/ac
6> portable
My Cons
<1 bulky & require a vehicle to transport but portable
<2 require multiple people to assemble (most time is done in pre assembly cutting & taping a sto make setup easier at site)
<3 large flat footprint needed
<4 To be perfect other creature comforts are needed (floor coverings, generator/access to electricity for ac/swamp cooler if in extremely hot/cold locations)
<5 little ventilation
<6 susceptible to damage from wind or snow
< 7 not mobile once erected (like a camper/RV/bus) & hard to blend in as anything other than a shelter
