Tangled

My roommate Mary is apparently a student of classic fairy tales, and brought a group to go see this. Not bad for Disney fare, but you're not missing much if you skip it. As usual, I have a few spoiler-laden questions and comments.

-Length of her hair varies really dramatically from like 20-30ft when shes running in foreground, to like 200-300ft in for example the canyon swing scene.

-If cutting Rapunzel's hair undoes all the healing she did on the witch, then shouldn't the male hero's palm gash reopen, and the queen keel over?

-It seems pretty clear that the witch had home-steaded the magic flower as a natural resource, and the king stole her property. Benefit of the doubt, the circumstances of the soldiers' discovery did not lend itself to thinking this flower had been cultivated by someone for 100+ years. Clearly, witch needed to confront the soldiers immediately and stake her claim before the irreplacable flower got ground up into a poultice. If she had, this could've ended with a tidy Coase theorem parable.

-Lastly, can Rapunzel self de-age? If Rapunzel is herself going to age normally and die, then the witch is just buying herself another 60 years or so, which I guess is worth fighting for, but not an immortality strategy. In any case, what does the witch get out of all this? She is just living for its own sake, with no ambition? She has already lived a Gollum-like existence in a forest lean-to for over a century, and then she's just going to sit in a tower for as many more decades as possible? She's not even making canny compound interest investments!
