I think there are cases where the company spends pretty much all the money trying several pivots and never comes up with a viable product; but the founders still want to try again. At that point, if the company really isn't worth anything (in particular, has no IP) then I can see that it might be acceptable to scratch it and start over.

Your point is well taken, though. I wonder if there might not be a middle ground, where a new company is formed with the old company owning some of its stock. This gives the new venture a cleaner cap table while not completely screwing the original investors.
