I would.
As for whether or not this sets a precedent? That depends on what you mean. For music? she already has. For cinema? As in, will more artists go around the studios and just work directly with cinemas? Probably not, as most artists don't have the clout of Swift. Now if Springsteen wanted to do what she did? Maybe. But if a smaller act like Of Monsters and Men wanted to do it, the studios would be laughing so hard the band wouldn't hear them say Komast héðan!
Taylor went around the studios because the studios wouldn't work with her. The film studios act like any other big corporation, they want what they want on their own terms. They do it because they can.
Remember though that lots of independent films are released that aren't from the large studios.
@dioxide45 is essentially correct, Swift funded the film, but it mainly consisted of editing, sound mixing, and graphics so it wasn't like she was paying the tab of the next Transformers movie. Plus, by going around the studios, she acted as Producer and gets to keep a large percentage of the profits with the rest going to AMC/Cinemark.
