Why would Durant leave a better situation with a better supporting cast for a new team, new city, with lesser teammates? And yes, Boston, even with Cousins, is not a better supporting cast than Westbrook, Ibaka, and company. The reason Washington is pretty much the only other destination mentioned for Durant is because that is where Durant is from. Durant isn't leaving OKC unless it is to go home and/or he goes to a clearly better situation (like Aldridge going to the Spurs). Boston is neither of those things even with Cousins.
