To answer your last paragraph, if my party won power in 2016, I certainly would not object to the Democrats refusing to cooperate.
Well then, your doing a pretty horrible job of being partisan. Any partisan Republican worth their salt would blast the Democrats for filibustering or obstructing anything. Maybe you should start drinking your own Kool-aid. (Of course, I 100% expect you to change your tune once your party is in power, but that's beside the point.)
Most of the rest of your post isn't that important. You demonstrated how a hyper-partisan system could theoretically work in the U.S, sure. However, two parties constructively working out a deal that is acceptable to both of them is vastly preferable.
Why?
A.) It better represents the interests of the electorate. A compromise between the two parties will result in a bill somewhere in the middle of the political spectrum, and be supported and liked by a larger portion of the electorate.
B.) It will lead to a less hostile and divided country.
C.) A decline of partisanship will lead some voters to consider candidates for qualities other than their party label. Incompetent or scandal ridden politicians can win in safe districts due to high partisanship.
