Sure you can do that, but I'd say in the general case "it depends". If your needs are fairly basic, that's probably the best approach. You also eliminate some overhead (piping messages through a middle man, operating said middle man, etc.). But it's my understanding that if your needs are a bit more involved, the complexities of building a solid queue mean that it'll take time away from building your actual product. In that case, you may be better served by an off-the-shelf solution which already handles the corner cases and is good to go. I think this is the usual decision between using an external product and rolling your own.
