If so, now imagine how great this car would be with a folding second row.
That's really what made the original Model S great (D a little less) in this sense, it is phenomenal what can fit into it - the deep frunk is a great addition to an already insanely great trunk.
Model X without a folding second row will just remain a little bit behind that greatness, because even an insanely great frunk as an addition to a mediocre trunk will end up being mediocre overall.
I think only a minority of people need that much storage in one spot. The MX will have way more space than any other SUV out there alltogether, with the gulf rising drastically when you actually take passengers along.
People who need a lot of hauling without passengers buy a pickup truck (2, maybe 4-5 passengers). People who more often haul people over cargo buy SUVs/CUVs. People who have to haul large quantities of both buy full-sized vans. I don't think there's much an intersection of people who A) Haul passengers often but not always and B) Haul very long pieces of cargo often, but never haul large volumes of cargo that can be separated.
People who buy competitors pay 4-5x as much for fuel and also can't go 0-60 at McLaren supercar speeds.
What competitor in a similar price range would you use over a Model X, and is a competitor really going to provide a better experience? If I were in your shoes, I'd just buy/rent an appropriate trailer (the MX can tow!) for those rare times you haul very long objects, and if you those occurrences are not rare then I'd recommend you go with a pickup truck instead of a CUV.
