Part of my point with that (the part that I totally didn't in any way voice or even hint at), was that you needn't fear the straight draw all the time. First off, if you're playing a typical player, you can dramatically narrow down the range of hands they might call preflop with. In this situation, A 3 9 isn't scarey at all (whereas playing you or Rippy, I'd be a bit fearful here).

Even on a flop of A J 6, where KQ (a likely calling hand) gets the draw, they have 4 outs to make it. If it doesn't come, you win. Even if it does, you have (1 + 3 + 3 + 3 =) 10 outs to your by-the-river boat (so about 40% to make it on the flop; 20% on the turn). You want to protect against a suckout, but it's not the dire need it seems like. A flop with connecting cards (like yours was) rather than the auto-gutshot is a bit more dangerous, since it offers them about twice the chance to make their draw. Either way, destroying odds here is easy...just play it right.
