If this was able to achieve any arbitrary number score or even if it was able to consecutively hit scores beyond what a decent player could get, I would agree. But just because playing random works somewhat doesn't make it bad. I'm sure there are new players who would lose in Go to a computer that only placed pieces randomly in valid positions. But with a little skill, another player (or designed algorithm) should be able to almost always beat such the random algorithm.
Yes, of course, in the sense that it is not the best game possible. But it is much less bad than this game. Look at what a Chess AI does and look at this AI.
