Wrong:14:
1. It is harder to verify that a bowline is correctly tied than it is to verify that a figure 8 is correctly tied.
2. Thebowline is more susceptible to coming loose than the figure 8.
3. Thebowline can come undone if the loop is loaded in a pair of opposite directions off the axis defined by the standing part of the rope (for instance if you clipped a sling from an anchor to the loop.)
1. Not if you take the time to know your knots.
2. Not if tied and used properly.
3. And, don't forget, cinches down if both the free end is loaded, making it very difficult to untie. If there is any possibility of the free end becoming loaded in such a manner, then I highly recommend a butterfly knot. As a matter of fact, in high-angle situations, I believe a butterfly knot should always be used when needing a fixed bight anywhere in the rope away from the ends. It's too easy for an unforeseen situation to tempt you to load the free end, or, as you pointed out, load the loop in a second direction.
In my opinion, your original recommendation that the OP buy climbing webbing, and learn a special knot to tie it, is absurd. The water knot is pretty much unique to climbers, because it's about the only knot that will hold in webbing, and still be easy to untie. If JahJah were a climber, he would already know how to tie it. If not, I suggest he learn a knot with more applications.

He's hanging a hammock in a dorm room, for pete's sake. Not a porta-ledge on a monster wall.
JahJah, take the end of your cord (any old cord you have laying around, as long as it will support your weight, or buy some cheap clothesline), double the end back about a foot, and tie an overhand knot in the doubled cord. Simple, cheap, and will hold your butt off the floor for as long as you want to use it. You won't be able to untie it, but who cares? When you're done with it, cut it off and throw it away.
